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.
Do blind people dream?
Dreams in blind people depend on the nature of their blindness. Individuals who have born blind will not have visual dreams instead they have night mares, most of them revolving around their challenges faced during the day. They experience dream through their sensory inputs like touch, smell, noise and emotions. People who were blinded after birth can experience visual dreams based on the visions or images that they have seen.
Do animals dream?
Research conducted by various scientists show that animals do experience dream while sleeping. They also experience similar sleep stages like human beings - REM and Non-REM. If you have noticed a dog sleep, it might sometimes wag its tail, this indicates some response to its dream. A study was conducted in a cat by removing a part of the brain stem, which will not prevent it from reacting to the dream during REM. It was noted in some cats they were aggressively chasing mice as in reality.
