Hey there,

You know, all these techniques that you read about, requiring you to do this or that are, in my opinion, all just techniques that help focus the mind on lucid dreaming. But its the mind where it eventually happens, so no... I don't think any physical limitations should make it more difficult to Lucid Dream.

Additionally, for everyone it is always a matter of finding out what works for him or her. What works for one person doesn't necessarily work for another. Personally, I find that doing these sort of dream-checks that you describe doesn't help me lucid dream at all. In fact apart from keeping a dream journal, I really don't do anything at all that requires taking any sort of physical action.

I guess my point is: find out what works for you. The most important parts are wanting to lucid dream and being willing to invest time and effort into it. If you got those two going for you, you're off to a great headstart, and will probably find a way to manage to Lucid Dream sooner or later.

Hope that helps,
