The test I use to know if I'm lucid is whether I'm both aware that my physical body is in bed and that I am focused in a nonphysical environment.

So, it doesn't matter if I have sight. Often in dreams I can see but I'm not really lucid since I'm not aware I'm in the dream. Yet in OBEs I often am blind but I am lucid since I know what's going on.

It sounds like you were using the 'radar' sense that comes with some OBEs. For me it's a volumetric sense that enables me to somehow know exactly where everything is with at least as much precision as sight, even though I can't actually see anything.

So I don't think your experience was just trickery of the mind, but of course I can't know for sure since you were the one who had it.
