I don't know about doing RCs that involve feeling something. In my dreams my sense of touch is fully in tact. For example, in one lucid dream I was beating up on some suckas and I felt my elbow take the shock when I dropped an elbow on one guy's chest. If someone were to pinch me, or I pinch myself, I think I would feel it. The only reality check to work for me has been the mechanical failure. A lightswitch not working, for example.
