Wow ~ I can't say that I've ever experienced anything quite like that. Maybe a couple of seconds of something similar -- but nothing like that! I wish I had!
That sounds pretty exciting to say the least.
i don't think it's anything that needs intense therapy, but if you're already seeing a therapist, I WOULD mention it to him/her. I don't know what I would call it, but it may be something that you would want to talk about.
You certainly have a way with words. You should try and work on that, and perhaps think about doing some REAL writing. What do you think? Or have you already done that? Think about it, huh? Just an idea.
God bless and please take care. Hugs, Lee
