My Panic Attack Solution

Very distressing experience. For several hours (the entire day, really). My mind got very jumbled up and irrational. Everything felt strange, slighty foreign and surreal.

First I believed that nothing existed outside my mind. Everyone and everything was only created by me, and had no real existence outside of me.

Then I thought that I was living in the imagination of a superintelligent being/alien (?!).

Then I thought I was an advanced intelligence having a detailed conscious dream, and that I was stuck in it and wanted to get out. I thought that dying could possibly wake me up, like it usually does when I have dreams in "this" body.

This whole thing was extremely disturbing and I felt really worried/sad/anxious/panicky afterward. It lasted for most of the day. I still feel that way a little. This has happened before with varying intensity and duration.

Is this related to some mental disorder?

I currently have clinical anxiety as well as likely depression. I’ve had a full-blown panic attack before, but it wasn’t really like this. What worries me is the thoughts of dying during this, as well as feeling on the edge of doing something really destructive/dangerous, just to "test the limits" of "this" reality.
By the way, I have never taken any sort of medication for depression etc. I’ve never used any street drugs either.
Jody: I have experienced no trauma that would cause PTSD. I don’t get flashbacks or the other symptoms of PTSD either.

It’s dissociation with depersonalization-derealization episodes– just for fun.
