Be as dry as you like Billy, and please free free (anyone) to contribute to this thread, on the general topic of drugs opening us up to these kind of things.
I half expected people, to think along the lines of "he imagined it all - on drugs - what do you expect", but what you and others have said here, is in line with my own thinking. I know it wasn't imagined. That whole period of my life was like having my house burn down, seems really bad at the time, but I am a lot wiser stronger for it now. Quite a few really strange things happened around that time in my life ...
One time I felt the presense of a lesser, more earth bound entity (it was non physical but it had more 'solid' energy, it felt closer to our physical plane of reality). I remember at one point, shortly after I became aware of it, it shot out of me, and went in to my dog. My dog was going mad well before this, he could tell something was wrong, but as soon as it came out of me and went in to my dog, he lept off the ground and spun round, maybe like twice! As if he was having a stroke (sadly, he did have a stroke for real, later in life).
Another time, I remeber looking at a clock, and an instant before I did this, I KNEW it would be exaclty 12:00:00 to the second, and it was. I remeber this kind of thing happened a bit. I may have been sitting on a bus, and I would just know there was someone on the pavement outside, who was 'awake', and I look, and see some rasta guy or someone looking at me in a knowing way. This also happened to me in India, while I was in a taxi, but the guy was like 100 meters away, so I imagine he was very energetically strong to make the connection at that distance.
I also had exprerience of seeing people who I had a strong feeling were 'awake', but involved with some kind of secret organization, perhaps with the purpose of the mutual benefit of it's members (and sod the rest of us), like a global elite of people controlling the world. Sounds far fetched, and I can't say how true this is, just that it was my distinct feeling at the time. The guy was dressed simular to the agents, in The Matrix, also, the film 'They Live' reflects this same theme.
Some other really really strange things happened; and I am very much of the opinion that one needs to be a man of power to process such things, rather than to be blown here and there like a leave in the wind. If a person is a man of power, then I can apprecieate venturing in to such realms may have some value. It's certainly a serious matter, I feel, and is the reason I would always caution against drug use. The term 'man of power' is from the Casteneda books I think, I'm sure it applies to the ladies too.
As an aside, the song Riki Tiki Tavi (mongoose is gone), by Donovan, in the version I have, there's some good points made. Riki Tiki Tavi is a mongoose who kills snakes (in the Jungle Book), in the song, he's gone, and won't be coming around for to kill your snakes no more ...
Snakes, being, the government, the school, religion, in general the establishment (which I believe is established with the purpose of keeping those in power, just where they are, it's the power structures that control the world economies etc). So we have to kill our own snakes. Also, I feel this is true, very much so, in other realms. You certainly can't go relying on Jesus or the Tooth Fairy or such like; not that I don't believe in Angelic beings, just that, for me, I found that I was on my own.
Hope I don't sound nuts!!
