visualizing aside from lucid dreams? and light sound machine

Hi

I have managed lucid dream in the past, but i’m interested in visualisation generally.

With a lucid dream I have to be in a deep sleep then become half awake. I have managed it successfully a number of times. I was pretty good at it when I tried…(

Aside from a lucid dream, I can’t visualise a thing, and that’s what bothers me.

I’ve tried 2 light sound machines. The mindlab orion, and the Proteus, but I still just don’t get any picture or image appear in my mind at all. No matter how simple.

Does anybody have any thoughts on that? particularly anybody with that issue that overcame it!

Interestingly lucid dreaming is the one thing where I -can- visualise. But not really something I can do quickly… I’d like to be able to visualise within say 10min or 20min whether tired or not. I’m willing to try gadgets that might help, but two I tried have not made any difference.
