Okay now a really fancy way to give yourself Visual external light Signals when you enter Dreaming, REM-sleep to giving you an hint that you're Dreaming is the DreamMask.

Now I came up with a simplyfied version of it that could have been made in 2000 BC.
Make 2 Pads of a soft and somewhat thick/heavy cotton or textile. The pads should each be such a size that you can put them over your closed eyelids and they completely cover your eyelids + puttting a little extra weight on the keeping your eyelids down. Now on the outside of each pad, in the centre, is a little Ring with a Catbell on it. Maybe the sides of the pads that you put on your closed eyelids should have nobs or a rubber grip layer to actually attach them to your eyelids so that when they start moving, so will the pads.

When you enter REM-sleep your eyes will start Trembling and Shaking and let the 2 Catbells Ring. This you could use as an Auditory Signal that you are Dreaming. And if the bells don't make enough noise you could try different ones or more. Sort of: When the Bells ring you are Dreaming. Just be wary for the sound of bells anytime of the day and night.

I have drawings of this Concept. I will Scan them soon and post them in this Topic. That should give a better idea of what exactly I'm talking about.

How about that people?Something worth giving a try?
