Question

why our brain consist so thougts while sleeping

Answer 1

While you’re asleep, the brain is busy forming new memories, consolidating older ones, and linking more recent with earlier memories, during both REM and non-REM sleep. Lack of rest could have a significant affect the hippocampus, an area of the brain involved in memory creation and consolidation.

For this reason, sleep plays a very important role in learning — it helps us to cement the new information we’re taking in for better later recall.
