Oh hun, your panic is palpable.

I'm glad you talked to your T about this - and as long as it is bothering you, keep talking to her about it.

I can't say one way or another whether this was a dream or not. It doesn't sound like psychosis to me. Weird stuff like this happens to me a lot - and my issue is dissociation / PTSD. I don't know if thats the same for you, but your T will help you disipher it all. That doesn't happen quickly, but I have learnt to kind of accept that at the moment I don't know what is real and what isn't - but one day I will, and Im working towards that day. I spent months and months going over every detail and in a spin about it, but now I can kind of function normally and have these thoughts in the background rather than taking over everything. I mean, I still have my moments! But it does get easier to manage.
