well, like the title says, I'm having problems keeping lucid.

I'll be in a dream and not suspect a thing when suddenly I realise that I'm lucid. So I say to myself: "ok, don't go hyper, keep lucid!"
So I spin and rub my hands together but whilst I'm spinning, everything starts to go dark and I get annoyed because I'm doing what I should do. oh yeah, then I wake up.
Help?
