Reading “why we sleep” by Matthew Walker and he talks about non-REM and REM sleep. he postulates that non-REM sleep removes the superfluous/unnecessary and the REM sleep giving details. He uses clay model as a metaphor. Removing excessive and creating the rough shape is non-REM while adding details and connections is REM sleep. Perhaps meditation acts as that remover of non-REM, separating yourself from your thoughts/emotions so that you can be more objective, cutting some of that superfluous. Not to say emotions are superfluous, but you also don’t want to overshoot and have it excessive. That can lead to unhealthy associations/conclusions.

As an aside, I don’t think emotions are inherently bad. However, emotions can result in stimulation and as being who at times seek stimulation, there is the possibility of excess.

I feel like there’s this narrative on how important emotions are and how you should feel, which I believe odd true to an extent. But I feel that generally speaking, people have problems of feeling too much. I think society has a tendency to exploit our emotions and continually tapping emotions makes us more prone to unrealistic emotion expectations/responses. Just my two cents. May very well be wrong
