Since its existence, suicide is a symbol of the destruction of the world. As widely popular Sartre’s doctrine preaches it, the value of reality is exclusively the scope of existence. However, in some cultures, like Japanese, suicide for ethical reasons is considered an honorable action. Dreaming of suicide could symbolize an aggression against your person which you punish for some motive or need to remove an aspect of your character with that which you do not like. It also indicates, in some form, that you resist accepting the problems that are affecting you or living in a way against your desires. You should interpret this dream as a severe warning: you are not upholding your commitments and you try to avoid reality. Lastly, the act of destroying an object with which you identify could be a sign of the latent desire to suicide. Oneiric oracles say that this dream foretells deception.
Improving memory can be done in a number of ways, and one of those is by having a good night's sleep. During sleep, your mind is still busy and going through the process of consolidation, where it strengthen your memories as well as the "practice" skills, which you have learned while you're awake. According to the associate professor at NYU Langone Medical Center, Dr. Rapoport says that something happens while we are all sleeping, and it helps us learn things better. Thus, if you're trying something new, you can perform it better right after you sleep.
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.
