There is an image streaming group that is now available through Yahoo. The participants support Win's claim that you need to have a "listener" to accomplish the best results. There is something about knowing that there is a listener that provides better reinforcement to the process (gives it validity). I guess your inner mind gives it more attention when it knows you think enough of the process to share it in some way. The group seems to be divided on actually listening to the tape. I'd say that it's less than 50% that actually listen to previous streams.
There have been participants who have been willing to share their image streams and it's a very interesting read. Go to http://groups.yahoo.com to find it. I haven't done a lot of image streaming myself, but I did feel that my streams were higher quality when I had a listener. In my case, I was using my laptop and Dragon Naturally Speaking. The results were hilarious (because of translation errors) but it didn't matter to the streaming process. The images were definitely sharper and more defined when there was a listener of some sort. I'd be interested in finding out how people experience the visual process since I'm not highly visual.
The participants have given high marks to Win's "Einstein Factor" tape set that is available through Nightingale-Conant. I've been holding out to see what LS is going to provide with the Genius Code, but I'm not sure I'll hold out much longer...
As far as the IQ increase, there seem to be differences of opinion on that as well. The biggest sticking point appears to be whether or not it's sustained. I side with the group that says, "Who cares if my IQ increases? If my creativity improves and my intuition strengthens and my visualization skills improve, that's enough for me."
Good luck. Let us know how you get on. It would be interesting to find someone who uses image streaming as an activation method.
