Absolutely. It happens often enough to keep me addicted to Domme space. If I had to venture a guess at how often I would say maybe an average of once every two months. Like you mentioned in your reply, it most often comes when I don't expect it. I've even had it happen in sessions I was not looking forward to - then something happens - usually a response to a phrase or action and the energy changes and we are both off to the races.

Roleplays are a great opportunity for this. I have a love/hate relationship with roleplays (which is probably fodder for another post) and I remember an interrogation scene that I was not looking forward to. In general, I love interrogation scenes but this one was complex. It was a military capture that included the male sub (client) and a female sub (mine). It was a 2 hour session, I had never sessioned with the guy before, he was a stickler for detail (rank, address, uniform, etc - he was active military). There was a great deal of prep and by the time the session rolled around I was almost dreading it.

I noticed early on that when I threatened to torture his female subordinate that his reactions become more genuine, so that's the avenue I went down. At some point it wasn't acting anymore and that is a very difficult sensation to describe. We all "believed". We were lost in it and it was magic.

These types of "magic moments" happen more often for me with subs I don't know but there is another type of scene where I can attain that as well, usually with clients that are very well known to me. It happens when boundaries are pushed and permanently moved - most often in S/M play. I remember one such experience during a brutal caning where I became so light headed that I had to sit down. It was an amazing experience for both of us.
