Try listening to the same song over and over and see what happens to your brain-waves.*
Try staring @ the same picture…
*During times of great fear, I notice two things:
•I get a song in my head I’m not particularly fond of, and
•It can play in my head, sometimes for a couple of days -I find this sort of pattern especially stressfull**
**They say a man can’t hold 2 thoughts in his head at the same time… There have been times where I can think about something at the same time music is going on in the background in my head and… do something out in the real world -albeit something fairly simple of course. When things are really bad I wake up with a song already playing – as if it’s been going in my sleep.
