I don't know if I've ever seen a thread about the mental state(s) of performing (by this I include practice, live, and/or recording). For me, it's a balance of two mind-states. The first is an hypnotic state, whose focus is totally on the moment, the feel of the jam, responding to what's happening musically etc. The second is a a conscious state, that is keeping track of where I am in the song, what changes are coming up, and trivialities like making sure I don't fall off the stage, etc. When I get sucked into the first state at the expense of the second is when I miss changes and play clams. I'd like to hear how others think about and/or manage their mental state while playing.
