Thanks for the replies.

So, I decided to have another go at it a few minutes ago (against the likely good advice from the above post). It wasn't really an extraordinary experience, just some rather bland visuals at first which got a little better as it went along. But at some point, I found myself in what appeared to be a stadium or arena used for racing. There was a track, grandstands etc. I'm not really sure what the symbolism is.
But anyway, even though I don't recall seeing any entities, I was most definitely communicated to. The message was telepathic in nature, and even though it "sounded" more or less like my own voice, there were at least 2 distinct ....whatever they were....speaking in unison and delivering the same message. And I quote: "Just shut up and listen."
OK, I thought. Now we're getting somewhere. So, I did my best to quiet the internal chatter, and shortly thereafter the message I received clear as a bell: "You need to abandon your stupid, idiotic thought processes." And then just a short while later: "Follow me."
The trip was pretty much over at this point, but I stayed in somewhat of a meditative, half-asleep state to try to figure out who I was supposed to follow and to where. I wasn't able to do either, but I was able to hang out in this visionary state for longer than I've been able to for quite some time. So that was good.
Now I need to work on figuring out what thought processes they were talking about. I have no idea how to do that. Even if I did, exactly how the hell is one supposed to abandon a thought process?????
