Dreams

i have always wondered what is the purpose of all the dreams we have...i mean there should be some reason we have them...research hasnt progressed a lot..i think its a very personal thing...here goes my version...a very far out thing...
Some how i feel that what you think(is right)...is what happens in your dreams(by the way...me sipping on some vodka right now)of course there are dreams u cant control...that subconscious mind thing starts working overtime so as to say...all your fears will get converted into real in the dream...all this only when you are really anxious...but you can control what you dream when you are in a good state of mind.....
i have had many dreams and been fortunate to remember some of them...have woke up in the middle of some...nightmare is da word...had this dream during childhood about me and stone cold trying to find rikishi in order to take revenge for the car accident...now i feel like laughing
looking back ...but todays dream was no laughing matter...was about her...sometimes dreams mean nothing....yet they seem to be so real
Wonder if life is a dream.....if we actually wake up when we die...can never know if thats the truth...wat say...?
