dream feelings

hi, i just have a question,

how is it possible that we feel pain and stuff in our dreams:
like i had:
- i was shot by 2 MIB's , i could feel the bullets and its impact
- when i've got snake poison all over my body, i began to shiver (?) and i got it very hot and pain
- i was bitten by a vampire, when she bit me i felt a nice warmth all over my body and i was paralized, it felt very nice but painful

im just asking
thx
ciao, jornt

It's like something dealing with the subcoinsious mind. If the dream is vivid enough it would reflect pain from the dream onto the body.

hmm thx, but its still very weird ( i think ) but thx anyway
