I have not yet successfully APed yet but I have gotten to the point were I feel like I am and have vibrations. Well when I usually try to AP I do it to sounds, I use this preset from BrainWave Generator http://www.bwgen.com/presets/desc570.htm I also listen to a few others but that is the main one. This Friday me and a few friends are all gonna listen to it and we want to see if one of us can get out. But I have heard of supposedly helping people get out so if one gets out but someone else is halfway between you can somehow help them. If anyone has any helpful information or knows how to help someone get out, I would appreciate it if you would post. Thanks :D
I tried with some friends once. We didn't even get the vibes but give it a go and tell me how it turns out.
