@whirly expression of an emotional explosion is a punishable and undesirable behavior in one self t. Brain
along with dreams being internal analysis and essentially summarizing of recent and not so recent events and emotions, it is simultaneously also a internal training ground for future plausible events. " I great fear of bear monster i see yesterday, how i can ambush and spear bear in head, what would i feel then, how might i react then, how might bear react"
an amalgamation of all these run off functions, each running at the same time and affecting each others, cementing certain learned behavioral patterns, or attempting to alter them if the simulation causes excess stress
that's at least the goal, if the eepy system ran perfectly,
i think my screaming in dreams was from a feeling of helplessness to change several parts of my life. An attempt to alter my behavior with regards to expression of very negative emotions, an attempt which failed for very very long and caused stress each time. Perhaps each time i felt that stress, it helped undo a bit of that foundation where i was incapable of screaming at someone in real life
Perhaps a little bit closer to the light with each nightmare suffered
