My problem with visualization is sleep posture.

I think I can visualize very well but only if I lay on my back.

The problem is that I cant sleep this way because I don't breath well. I normally sleep on my side, but in this position its weird to visualize because I have to imagine the landscape rotated 90 degrees so its aligned with my point of view, and it doesnt feel comfortable.

Any help with this? do you visualize while laying on your side?
