I've red about special chamber, that is filled with salted water (enought to make you float) with total light and sound isolation. I bet doing recapitulation in one of them would have much greater effect.

I've always been interested in these "isolation tanks" ever since I watched the movie "Altered States". Here's some more information on them if anyone is interested:
