Yes, I used to trance out very frequently. For years. They lasted for hours and sometimes days.
I met with a trance master who directed me on this. I wish I had found him years prior to when I did. He suggested something radical, although it made sense to me. He suggested that I go into a light trance during the times I was healthy (not affected). I would light a candle, stare at it for a couple of seconds until I felt my eyes unfocus. Then I would bring myself back.
It taught me a few things.
1. How to catch my body early in trance - before I went too deep
2. How to pull myself out of trance with repeated practice
3. How to direct what I was thinking during trance (as it was so light)
4. Going into trance with intention (thinking of something spiritual)
5. Giving myself a destination when I went into trance
My destination was a 'safe place' that I built. It was a place that I told nobody about. It was a place that I constructed that had 'safe' things there for me. Sunshine, beach, palm trees etc.
Not sure if this will be helpful to you and I know it seems counter-intuitive, but thought I would throw it out there for you. Best of luck
