Rhythmic brain buzzing

I know this topic has been posted on a lot but I’m still needing some reassurance. Has anyone experienced rhythmic brain buzzing as you’re waking up from a dream?  Mine pulses it regularly as if it is squirting hormones from a gland.  It’s usually accompanied by a stressful dream with a burning in the muscles and arms. And as soon as I open my eyes it stops.

 

Anybody experienced this rhythmic buzzing as they are waking up? It feels like it relates to cortisol or something..... is this withdrawal? I wake up all night long. Even more than when I was tapering... will this nightmare ever end??

Yes I have. I think it comes from excessive tightening of the neck and shoulders, sending the muscles almost into spasm and restricting blood flow.  Sometimes I hear my pulse in my ears, too.
