Why do we get dreams?
First of all,sleep is divided into two categories based on our eye movement:
1. Rapid Eye Movement (REM)
2. Non - REM
During REM,your eye tends to move around in all directions and brain activity is very much similar to when you are awake. At this stage only,dreams tend to occur the most.
This sleeping phase is usually encountered 90 min after our sleep and stays maximum for an hour. During the REM cycle,our heart rate increases,breathing becomes irregular and most significantly,our skeletal muscles get paralysed.
Waking up before the completion of REM cycle can lead to sleep paralysis.
Now,coming to the point,why do we dream?
Well,I'm actually not sure. But these may be some possible reasons for dreams:
1. Dreaming helps us form memories. In the sense,we have more dreams when we learn something new. Also,according to this theory,dreams helps convert short - term memories into long - term ones.
2. When we are awake,our brain is busy in dealing with many activities and therefore doesn't have the space to concentrate on things that bother our emotions. During sleep,the brain has enough time to sort out emotions and achieve a balance.
3. Dreams are our way of expressing emotions and desires that we suppress during the time we are awake.
