I tried this link, but it did not work. :-(

I've experienced the downward pressure on my "Crown Chakra " area. I can induce this state by meditation, it can become quite intense. Sometimes it involve "rapid eye movement" and on a couple of occasions I saw "Phenomes" or "Form Constants" These are associated with initiates who consume "Treptamine " based drugs though I have not ever consumed any. I have heard some of what I have just described as some kind of blockage of energy flow. If this is true I'ld be grateful for ideas on how to release this blocked energy.
