Apologies if this is a silly question.
I have been doing a little research on why we experience rem sleep and came across a medical article linked to depression.
The authors findings were that our brain engages in rem sleep to complete a cycle of thought- feeling- processed.
The findings suggested that if we have thoughts then feelings about an event or incident etc, and we don't process it or resolve it in waking life then it would be processed in rem.
If it is processed during waking life you are unlikely to dream about it.
This has me pondering if we could some how use that information to aid in lucid dreaming.
Although mainly about depression it does explain what i have found.
Does anyone have any thoughts?
