As you know - I am very interested in it!
I've had this beautiful normal dream lately:

I was in a sports-hall with a group of maybe 20 people and we were rehearsing a choreography, dancing.
When I went out to the loo, I saw colour pencils on the wall in the hallway, took them in with me - and somebody explained they were magical things, and one could write with them in empty space, in 3D.
So we did that - we connected all the dancers with a net of colourful shining thin lines, also connections to the room.

And then danced again. I felt all the other bodies - it was as if we were all one dancing organism, parts of a whole connected by these lines.
Amazing - never dreamt something like this before. It's even difficult to describe exactly what this was like - alien and beautiful, that is true for sure.
And a while before, there was this little attempt:

I had transformed my arm into a swan-neck with my hand as the head for the comp and lost lucidity in the process of growing the eyes into it, to try and wave it about and then see with four of them, and now I have that lodged in my head - what a coincidence...
But to try and convince my brain it needs to put in the work now and simulate a completely alien experience for me - doesn't sound trivial.
Anybody ever operated more than two eyes? Like growing two stalks with extras or something like it?
I'd like to try out what you describe - do two things at the same time.
What I also want to do is simulate an OBE, at least from within a lucid dream, and separate from my "physical body" and then look back at it from my "dream-dream-body", so to speak.
Maybe it would be possible to hold a double perspective in the process?
Very much looking forward to your further experiments - and wish me luck for mine!
Highly fascinating!
