"You can analyze your behavior through a dream...."
You must strive to examine your dreams, for they are a manifestation of the Holy One's guidance personally directed to you. Rabbi Shimon bar Yochai, of blessed memory, teaches (see Chapter Four of "Shaarei Kedusha)", that you can analyze your behavior through a dream, for according to what you do during the day, so is the dream ( Zohar, Chaya Sarah 130a). As Elijah said to Job, "In a dream, a nocturnal vision of the night, when a deep sleep falls over people, during slumbers upon the bed, then He uncovers people's ears and seals their affliction." (Job 33:15)
To the extent that a person is righteous, so is the truth of his dreams. A person will sometimes see visions of the heavenly worlds in his dreams, and there will speak with the deceased and recognize them; these will reveal to the dreamer teachings about the Garden of Eden and Gehinom, as it has often happened in our times.
Our sages say, "Rabbi Yonah said in the name of Rabbi Zera, 'One who does not have a dream for seven consecutive days is a transgressor, as the verse says, 'And he who has it will rest satisfied [in Hebrew savea] and will not be visited for evil.' (Proverbs 19:23) Do not read 'savea' but 'sheva' [Hebrew for 'seven']." (Berachot 14a)
Rashi, of blessed memory, explains that a person who transgresses does not receive the guidance of the Divine Providence through a dream. It seems to me that a dream will not come to him because his soul does not ascend on high while he sleeps. The soul of such a person is like the spirit of the beast that descends to the depths of the earth [paraphrasing Ecclesiates 3:21].
What is decreed for man in the heavenly worlds is revealed through dreams. As Rabbi Shimon bar Yochai explains: "Thirty days before a nation rises to power, or before a nation is to endure a disaster, the coming event is announced throughout the world. It is sometimes communicated through the mouths of children, or that of the simple-minded, or at times through birds who proclaim it to the world, but no one is aware of this because no one understands. When the nation is worthy, the impending misfortune is announced to the righteous leaders of the generation so that these may issue a warning; thus, when the people hear about the decree they may return to their Maker.

***************************
There are three types of dreams:
1. Dreams that have no real value, caused by your environment, such as food eaten or extreme temperatures.
2. A dream that comes to teach or show us something, similar to Pharoah's dreams, containing a message. These dreams are shown in abstract (picture) language and are the result of your soul having contact with an outside force. These dreams are brought to us by an angel (or perhaps a demon). Demons can come in the guise of rabbis or angels, just to fool us. It is easy to differentiate between the two because a demonic dream is always very confusing and agitating and you will wake up sweaty and fearful, whereas a dream brought by an angel will leave you feeling calm and peaceful, and knowing what you should do.
3. A prophetic dream is one when G-d speaks to you and you will intuitively know what to do next, because in the dream you were told clearly and that is what is known as "deja vu". It differs from No. 2 in that it is a true prophetic vision and you see a clear prophecy without the abstract imagery.
Chaim Vital writes in "Sha'arei Kedusha" that G-d speaks to every human soul, connecting through our dreams. In general, dreams are shown to us in pictures because this is the language of the subsconscious. When in deep thought we always think in pictures rather than words. But we must remember that the imagery is not necessarily representing the same thing as it does in reality.
For example, our rabbis taught that to dream of an "ass" means "salvation"; to dream of a cat represents either a beautiful song or a change for the worse, depending on the type of cat, to dream of an elephant means you will experience a miracle.
Chochmah = right side = sub-conscious = intuitive
Binah = left side = conscious = rational
Binah (conscious mind) deals with the physical word;
Chochmah (subconscious) deals with the spiritual world.
Our chochmah shows us images in our dreams, and our Binah interprets these pictures. Two people can dream of the same thing, but it will mean something different to each of them, relating to their own personal subsconscious imagery. In a message dream, the force communicating the message will result in your mind showing the form of pictures unique to you. Only you can really interpret this kind of dream. A true "dream interpreter" will help you to understand yourself rather than applying meaning to your images."
All dreams follow their interpretation
Never share your dreams with anyone unless you trust them to give you a good interpretation because dreams are self-fulfilling prophecies. If you dream of someone you know well and connected with recently, that is usually not an important dream. However, to dream of someone you DON'T know, or who you have no attachment to whatsoever means that this is a message dream.

According to ancient kabbalistic writings*, depending which day of the month you have the dream, the following outcomes are known:
(all dates are according to the Hebrew [lunar] calendar) *[Source:"Dream Interpretation" by Rabbi Shelomo Almoli - KTAV Publ]
Day of the month:
1st (new moon) All dreams will be turned to joy
2nd/3rd All dreams have no truth
4th/5th All that you see will come about but only after a long time
6th Will definitely come about, whether good or evil
7th Will come about after a long time
8th/9th Everything you see will be
10th/11th Will eventuate after time, and will not have any negative outcome
12th Everything will come about quickly and will be good
13th/14th Will eventuate within 18 days, and therefore offer prayer and supplication before your Creator, for He is forgiving and compassionate, long-suffering, and full of lovingkindness, taking back evil decrees.
15th/16th (full moon) Everything will come about after a time
17th Will eventuate in four or five days and afterwards you will rejoice.
18th/19th Whatever you dream will come to pass after a long time; but not everything that you dream.
20th/21st The dreams of these days lie; some say that if they come to pass, there will be rejoicing.
22nd In eight days it will come true
23rd Whatever you dream will be turned into argument and strife
24th Whatever you dream will be turned to peace and joy
25th/26th After 8-10 days this dream will come true and you should thank G-d
27th/28th/29th It will turn to peace and rejoicing
30th You will be in distress, but ask mercy from G-d and He will have mercy on you; alternatively, if you dream about any kind of trouble, peace will come thereafter.
Dreams dreamt on Shabbat will be accurate, since the "extra" soul we are given on that day leaves us more open to Divine influence.
According to the Talmud, Brachos 5a; the recitation of the Shema immediately before going to sleep is seen as a protection against the dangers of the night.
