Need help finding LD-related pictures.

Afternoon all,

I am giving a talk on lucid dreaming at a science fair in Wales next month, and have been asked to produce a poster explaining it as well. The only problem is, I am having immense difficulty finding appropriate copyright-free images. Any help would be greatly appreciated.

Anything just to break up large chunks of text.

try using diagrams of the sleep cycle, and get an abstract pattern for hypnogogic/hypnopompic imagery.

Hope I have helped

Excellent idea. Thankyou.
