FILD

Finger Induced Lucid Dreaming

Note: this technique has not been thoroughly verified or tested, and may not yield results comparable to well-tested techniques like MILD and WILD.

There's no risk in trying it, though.

FILD is a fine-tuned combination of IMP and WBTB that makes a full lucid dreaming technique. It was originally developed by an LD4ALL user named Hargarts.

Procedure

Perform WBTB. That is, go to sleep and wake up a few hours later.
Gently move your fingers as if you're pressing two piano keys back and forth, but without actually moving them.
After a few seconds (or, if you know you take a while to fall asleep, a few minutes), perform a reality check of some kind, preferably a motionless one. False awakenings are reported to happen often with this technique (and others), so make sure you double-check before assuming anything.
