I'm not sure if this belongs here, so move it where you see fit.

Of the few lucid dreams I've had, only one of them has been triggered by an RC. The rest has been triggered by a phenomenon I call "The Pang."

It happens whenever the thought of "Hey, this could be a dream." comes to mind in a dream. Basically:

1. The colors of my surroundings become brighter and more vivid.
2. A ringing appears in my ears.
3. I get a burst of energy.
4. My lower stomach becomes tingly on the left side.

All of this happens suddenly at once, and then subsides until all effects are gone, which usually takes about five seconds. The only constant is number one, with all of the other effects appearing in different dreams at different times.

Is this normal? Does anyone else expirience something like this?
