no I did not feel like I was struck by lightening. there was no pain in fact all there was when I dissociated was feeling numb, no emotions, not connected to any bodily sensations, in other words a sense of disconnection mentally...

in me dissociation was nothing like you see on tv, it was a very calm , emotionless, painless state of mind. numb, spaced out and lacking any kind of emotions or bodily sensations.

i did get the feelings you described but they were medication and psychosis problems in me. if my meds were not the right dosage or I skipped a dosage or if I was withdrawing from meds I would get lightening sensations, sometimes the lightening feelings in me were called hallucinations and delusions if there was nothing triggering it to happen example if I wasnt skipping meds or withdrawing from my meds but still getting brain zaps/ lightening feelings for no reason my treatment providers called it psychosis, in either case adjusting my meds solved the problem

my suggestion is if this continues to bother contact your treatment providers, they will explain what dissociative symptoms you have told them you have and those that they know you have, they can also check your meds and other reasons that could be causing this in you, and get you treated for it so that you dont have to keep going through this.
