You know sweety, I'm no expert, but you can dissociate (everybody can) from a period of life because you just can't accept what's happening, but do go through with it, like closing your eyes and jumping into a pool of cray cray, you know, like going through the motions.
If this happens all the time though, please consult your treatment provider.
My best guess, I guess.
Just to add, drinking and smoking (dope) like when I was younger had the same effect (even though I was screwed from the get go) ...not to say you are...just saying.
If this is a lifelong ordeal, then it just can might be a disorder, but as an isolated incident, totally possible as an isolated episode. I'm no shrink, just guessing like I said. Be well
