Why do we dream and......sometimes forget it when we wake up?

Answer 1

All of us forget 95-99% of our dreams for the very ordinary reason that we sleep right through them and aren't paying attention to remembering anything. In studies that compare people who recall several dreams a week with those who recall one a month or less, the biggest difference is that the people who recall have a greater interest in dreams and therefore a greater motivation to pay attention to them. For some reason, these people have decided that their dreams are worth remembering. The main reason we know "interest" and "motivation" are important is the high recallers say on surveys that they think dreams are important. But we also know it because some low recallers are stimulated to recall when they read about dreams or take a class on them. Some low recallers seem to be less good at tasks involving visual imagination, such as when they have to look at a picture of a building made of blocks and then construct one out of blocks that are sitting in front of them. There may be other "cognitive skills" relating to the ability to imagine things that are important, too, but the research is not yet completely convincing on this point.

Answer 2

Some people say that death is only a deep sleep and the dream is the second life..
Forgetting a dream tells that you are under lots of pressure in real life and your mind is always occupied with lots of things at once,so, it's exactly when you forget things in normal days like looking for your phone while talking with it.

Answer 3

When we're in the stage of REM we dream a lot. The ones we remember are those that occur just before we wake up.

Answer 4

Dreams only last a few seconds, even though you may believe you are dreaming all night.

Answer 5

because our minds are testing the brain to make sure everything is working, hence nightmares, and happys, anyway, our minds do not need them or need to remember them, it's not important or necessary to remember it so it gets thrown away
