Why do we dream? Help me Please;)

Explanation:

we dream because when our bodies are taking memories into long term, the memories from that day or the day before collide and make dreams. that is why they resemble things that have happened to us.

One widely held theory about the purpose of dreams is that they help you store important memories and things you've learned, get rid of unimportant memories, and sort through complicated thoughts and feelings. Research shows that sleep helps store memories.

The brain is so active when we dream that it is virtually indistinguishable from a brain in the waking state. Even so, the chemistry of it is entirely rewired when we sleep. Many scientists attribute this to the reason dreams are so strange and bizarre.
