i don't think it's a flashback, but this happens to me as well.....i just learn to take the poper precautions and find ways to come back to the present if it sends me into a flashback or to calm down.....

it happens to me to, i dont think its a flashback, though i dont have a name for it.

I used to experience those sensations when I was young, I would swear there was someone (or a few) there, but I was alone in the room. Sometimes the feelings were positive, other times negative... it did not happen very often, but I do remember it. I think now, I have too much 'noise'/worries/concerns/nonsense in my head, to be attuned to the energies that are around me.

When the energy was negative, I would conjure up thoughts of happier moments, people I loved & loved me, to try to ward off the negativity. I hope you are able to stay calm when those energies are passing through. They don`t stay unless you invite them...

I think that is why there is a Native spiritual practice that involves sweeping sage & sweetgrass around a room, called `smudging`.

I have this too at times. I don't feel its a flashback for me, but i do know that the trauma i experienced, is part of the reason i feel that way sometimes. I find that if i try to ignore it that just makes it worse. When it happens to me it usually helps if i call a friend or family member or visit with one of my neighbors. That usually distracts me enough to get over it at the time.

I've felt that way at times too. As far as it being a flashback, that would depend on your past.

Whenever I have had that creepy feeling, I always figured it was due to hyper-vigilance. You know that sensation of constantly being on the alert for trouble or danger. Our mind, emotions and especially nerves are working overtime. It is exhausting.

Hoping your doing better now!
