I climb into bed and put my flashing LED glasses on. I set the brightness very low and set the speed to approximately 12Hz. I slowly turn up the brightness to a comfortable level. At first, geometric patterns begin to form in a chaotic fashion. The patterns slowly move around and form into structures. They are becoming well organized, sliding around and fitting together like puzzle pieces. Once the puzzle completes the assembly of itself, the texture of the patterns melt into a solid white plane that seems to maintain sync with the flashing. As my brainwaves try to stay in sync with the flashing, small corrections cause the flashing to become very apparent for split seconds until my brain corrects the synchronization. In my experience of electronics, it seems that my brain was functioning like a PLL (Phase Locked Loop) circuit, making minor realtime corrections to maintain a frequency lock with the reference source, the LED glasses. After about 5 minutes, I remove the LED glasses while keeping my eyes closed.
All I can say is "WOW!" They didn't give me a headache or cause any problems other than making my eyes water a little too much. Maybe I had them turned up just a little brighter than I really needed.
