understand what you are saying.
have you checked about your meds if you are on any?
found for me that certain meds do that.

what are you doing before you go to bed?
are you in a "good place" or have you watched somethng on tv that is
too much action or loud or chaotic or something like that?
did you chat with ppl about things even if not triggering,
perhaps the subj matter was odd or something.

we have found that there are things we can't do before going to bed shows we can't watch
even chatting.

don't know if this is relevant. just some thoughts
