What is a dream ?

A dream is a series of images and emotions occuring without us letting it happen during certain stages of sleep. It has been said that dreaming is like going in to a trance.
     During a regular eight-hour sleep, the human body dreams for up to at least two hours. In your dreams, time goes much faster than it would if you were awake.



Why do we dream ?

In our dreams we use images more than words. We find ourselves doing things that are different than what we would do if we were awake. In dreams, we often find ourselves being chased or maybe even fighting someone such as an enemy of some sort. Antti Revonsuo, a scientist from Finland.said that we dream in order to rehearse behaviours of self-defence in the safety of nightime isolation.
     When were awake, it is very hard to remember every single image that we see. If we could remember every single image then it would clog our brain! Dreams sometimes show us images that we have forgotten until we are reminded while we are sleeping.Some images can be bad memories but some can also be good. The loss of a loved one can also show up in a dream regularly depending on how many memories you have with them. Dreams can create new memories with people whether they are dead or alive. However, these memories are not real of course. They can create good memories or bad memories with people. Although the choice is not ours.
