I know of many different things you can do during your reality checks, one of these is touching one's nose. I've formed a habbit; every time during a waking day I experience great emotion or I open a door, I perform a RC. I examine my surroundings, sometimes touch my nose, and try to fly ect.
Last night I gained lucidity not through a dream sign, but through remembering that I was supposed to be lucid. So upon becoming Lucid, I decided to do my reality check. First thing I did was touch my nose. To my suprise it felt very much like my real nose, except maybe a little smaller.
This is the first time I've performed this certain RC in a lucid state, and since it did not work, I was wondering if you guys have any alternative actions you do during a RC that are quick and efficient.
