does this ever happen to anybody:

ok, i am asleep and dreaming, then i realize im dreaming and i become lucid. so then im going about having my lucid fun, but then i start to think about my real body... i always think "this feels so real, i wonder if my real body is sleepwalking right now" then im too scared to do anything in my lucid dream because i think my real body might be doing something, and im scared to shout in my dream, because i think my real body will shoud and wake up everybody in the house... but when i wake up i realize that nothing happened.
