Your brain knows what is good for you – at least to some degree. One day, or should I say, one night I begun to experience visions. Like dreams, except the fact I was completely conscious during these, and I was able to clearly recall all the images, and even make notes. Another night I’ve seen a library, in which I had full control over my movements – so I’ve picked up a book, and I saw a symbol. Its meaning is not important, everything else is.
You see, your brain is an interesting tool for working with clairvoyance.
