Ok i just want to make this thread to emphasize the importance and effectiveness of this reality check. This is the only one that i ever do and its so simple and everyone knows about it but its highly underestimated.

Counting your fingers.

For those that don't know, every single time you dream, no matter what, you will always have one extra finger, on each hand. Throughout your day, remind yourself to count your fingers on one of your hands. Every time you notice something strange in waking life, count your fingers. The more you do this, the easier it will be to remember to do this when you are dreaming. It is such a dead give away that when you see this extra finger you will know immediately that you are dreaming and can proceed with dream control and stabilization tactics. Its usually always between the middle finger and the second finger from your pinky. There have been nights where i had no intentions at all of lucid dreaming, yet the often reality check will suddenly come into play due to the importance that my mind has given it during waking life.

That's pretty much it. Im sure this has been covered before but i just wanted to go into more detail about it because it works like a charm for me and i see no reason why it wouldnt work for anyone else.
