I have been having nightmares for a couple of months ago. i i have a bad dream atleast 3/4 times a week, they are really disturbing dreams, and i dont know how i even dream of these things. Im 21.

the worst dream i've had is probably the one i had last night.

i had a dream that i was little.. and i was with my friends, at someones house and they had a pool. everyone was having fun, and screaming. then there were fire works, they were really loud, but when the fire works stopped. all my friends were silent, and worent moving. Then one of them toppled over, and they were dead. they had blood comming out of their chest. ALL my friends were dead. i was really scared.  The people whos house it was came out. and they had a babysitter. and she took me inside the house. The people whos house it was were normal when they outside of the house, but when i went it, their bodies flashed into something scary, like a skeletop, or just a scary face, even their cat.

Im getting the chills even thinkign about it again. This is 1 out of my many disturbing dreams i have been having. does anyone have an idea as to whyyy this is happening??? im starting to feel crazyyyyyyy       

Water represents emotion.
A house usually always represents you, or rather 'the self'...your body and the attributes of your personality:
They symbolize our emotional and psychological selves. All of your experiences, stages of development, and parts of your conscious and unconscious life may be represented by that house. The house may be representing issues concerning a particular dilemma in your life, or it may be more general and comprehensive.
A unknown house suggests aspects of yourself you are not familiar with, and new experiences.
Being a child again is a representation that you long for the time when you had less responsibilities, and life was easier.
Blood represents life, and your energy.
Fireworks represent emotions that are intense.
Friends represent your social structure, and social acceptance.

Have you had an argument with a friend recently?
Have you experienced an extreme emotion, one you're not 'used' to?
Have you been stressed and you wish you could just have things the way they used to be?

Just a few ideas, good luck.
