Does anyone have any advice on how to stop a De-realization episode("I'm still asleep" or "Everything is fake")? Also, any help with Depersonalization (The left side feels alien and I feel like I'm a fake version of me)?

More specifically, is there any way to bring yourself out of a episode quickly but not noticeably? I would prefer not to have to explain my situation to others, and the episodes are getting more noticeable by the day.

The episodes usually happen at different times, so advice for both specifically would be very helpful.
