If a body is found in your dreams, it means that a situation is corrupting; there is something that smells bad and threatens to destabilize you. The corpse symbolizes the corrupt, those bad thoughts, hatred, and resentment that should be buried. That is why the dreams in which you become a corpse symbolize the desire of being done with a situation that concerns you.

Body reactions during sleep
Most of us must have experienced hallucinations or night mares. When we experience such dreams we are unable to move or react. This stage is referred to as sleep paralysis. This type of dream occurs in between wakefulness and REM. As it occurs during the REM stage, it causes complete muscle weakness preventing the individual reacting to the dreams.
Reading in dream
Sometimes you will not be able to differentiate lucid dream. If you want to be sure, try reading a simple sentence, if you are able to read then you are in wakeful stage if not you are in lucid dreaming. Studies show that you cannot read while dreaming or you will not find the repeated sentences one more time.
