It may be that you will go all the way and lose the link to the familiar world and be totally involved in the visions. Before taking LSD, be assured that if this happens, you will come back and it will be quite a journey. When the time comes, during the trip, you may find it very difficult to believe that you really will come back if you completely let yourself go in the visions. If you don't want to take that chance, you shouldn't and if you are not in a private, protected place, you absolutely shouldn't. The best visions I ever had came when I was tripping in a college gym watching a basketball game. I couldn't let myself get involved in the visions because I was in a public place, not a private, protected place.

Something that can easily be misunderstood. When someone is tripping and seems to be in a catatonic state, with glazed eyes and not responding to anything, it's all right. The person's eyes may be open, but they don't see you because they are deep into these visions and maybe having the religious experience or if their eyes are open, they might see and hear you, but they are so far beyond the context of verbal give and take that they don't even bother trying to respond and the people who are there have to understand this and that the person is all right.

You can get visions of events from your past and can relive the events exactly the way they happened, down to the finest details and relive the emotions. It may be something that you always remembered or it might be an event that you have completely forgotten about, but when you see it now, you do remember it and are amazed that it was ever possible to remember whatever it is. It might be a painful memory and emotional, but it can be very beneficial and therapeutic.

The person is remembering an event and reliving it, but at the same time, they have not lost contact with the present reality. They are aware that they are remembering and thinking back to the past and aren't actually in the past or lost there. The person may be reacting emotionally and realizing that some problem that they have had for years all stems from this past event that is being relived. They may see that for this to be a cause of a problem was ridiculous to begin with and here on in, it won't be a problem anymore. It should be noted that the person taking the LSD doesn't know, in advance, what visions they will get and can't control what they will be. They'll see what they see and they might not see visions of their past.

It's possible to relive your own birth and even the 9 months spent inside your mother's body. It sounds impossible because you can spend your whole life lying down on the couch talking to a therapist and never remember these things, but with LSD it can happen. The difference is that LSD isn't just talking but is the catalyst that opens up the mind and gets you in touch with the rest of the brain. The rest of the brain is the "approximately" 99.999999999999999999999999999999999999999999999999999999+ percent that the ego knows nothing about. That's a whole lot of brain. Stored in our brain is an intricately detailed memory of every aspect of the history of all existence. LSD can bring any memory into conscious awareness, whether it's a memory from earlier in your life or whether it's something from long, long before you were ever born. Our brain has infinite untapped potential. It's too bad that we don't know about it and make no conscious use of our brain beyond the trivial games of the ego.

Concerning the concept of the brain being an infinite computer that has a stored memory of everything that has ever happened to anyone or anything, Timothy Leary goes into this on page 138 of his book, The Politics of Ecstasy:

"Built within every cell are molecular strands of memory and awareness called the DNA code, the genetic blueprint that has designed and executed the construction of your body. This is an ancient strand of molecules that possesses memories of every previous organism that has contributed to your present existence. In your DNA code, you have the genetic history of your father and mother. It goes back, back, back through the generations, through the eons. Your body carries a protein record of everything that's happened to you since the moment you were conceived as a one-celled organism. It's a living history of every form of energy transformation on this planet back to the thunderbolt in the Precambrian mud that spawned the life process over 2 billion years ago."
