I've tried half-assedly to get lucid dreams around half a year ago, but this time is the first time I'm putting some serious effort into it.

Here's the problem. Now, my dream recall is still very bad, but I've been trying to do WILDS the last couple of nights anyway, but I haven't managed to reach SP. Not even close.
Every time I've tried I've been lying still for over an hour, but I never get that SIGNAL that I've read that you're supposed to get.

I tried this morning after waking up from a dream, the clock was around 9 in the morning. I lay still for what seemed like an eternity, I had managed to clear my mind, mostly, but absolutely nothing happened. I was sure that I had been lying there completely still for at least an hour, so I got up and looked at my watch, and it says 15:42.

What am I doing wrong?

This thread is probably very messy, but I'm hungry and can't be bothered to make it neat.
