Precognition ran in my family. Perhaps up to 20% of the world's population has psi abilities; precognition seems to be the most common. A house wife in Florida was on the NBC news one night because she got herself and her daughter out, just bare moments before a small plane crashed into their home. Actress Lindsay Wagner cancelled a plane flight shortly before it took off; minutes later that plane crashed, killing everyone aboard. Even Abraham Lincoln had dreams about his assassination a week or two before it happened. And the list goes on.
A neurological study done on psis has shown that both clairvoyance and precognition work at a brainwave frequency of 8.3 Hz, an alpha frequency. Alpha frequencies are the easiest to get in to with meditation, biofeedback, binaural beats, hypnosis, and even some drugs.
I used to know a lady that taught a community college course on how to develop such abilities, but the thing about precognition is that it must work for you unconsciously: it would literally drive you crazy if it worked all the time for you consciously-- you'd could never tell the present from the future. I had that happen once and it's disturbing to have time slips.
If you really want PC, the best way is to go to a hypnotherapist and tell them what you want. Most hypnotherapists could condition your subconscious in only a few sessions. That's costly; anywhere from $60 to $120 each session. But a good therapist could program you for self-hypnosis; with that you could develop any psi ability you want, whenever you want. There are a couple of good free hypnosis script books on the Internet; some have script made especially for developing ESP. If you learn self-hypnosis you can tape such a script and play it back for a few weeks until you find yourself with PC. But be careful what you wish for: being a prog can, as someone once said, "be a gigantic pain in the butt." Once you become precognitive, you can't turn it off. This is annoying when you know how movies and TV shows will always end. You can also sense if people close to you are going to die. And if it gets out of control, you might find yourself becoming a time sensitive, seeing freaky things that Normals can't usually see.
