My lover & I are involved in bdsm & are RACK players. We've, for the last yr, added a blood choke hold, as opposed to air choke holds.
It's been very successful.

The last time tho was not successful because of things that I saw while I was out. Very strange things & glimpses of my past which I was not expecting. It had frightened me so badly we've not returned to this action for several months.
We're both extremely aware of my triggers & what to do when I'm triggered. If I feel I do not have that control everything stops. But here is unknown territory that can't be "controlled" as far as I know.

Has anyone ever experienced glimpses of their past while unconscious & how did it effect you?
Did you handle it like any other trigger?
Were the pieces factual or fiction?
Do you feel that there is a way to control the unconscious say through a series of steps?
What did you do afterwards?....bec for me, it felt very real.

I do not wanto lose this part of play & we've discussed that this could be an area to safely explore. But how do you safely explore the unknown knowing it might cause damage in the present....yet I'm still intrigued.
I feel the more we put it off the bigger the fear might get & this is a huge concern because fear stops everything.

Thanks
