Extra Sensory Perception, yes it's real. Everyone has it in fact but it's only evident in people with an Average or Above Average IQ, and on the flip side, people with odd mental disabilities (I forget which ones so I'll leave it at that). These people tent to have great memories, or at least a different way of thinking. In a nut shell, they just have better short term memory.
Other types of people who tend to have ESP are those who have been dead. Literally these people were in some sort of accident and pronounced dead... only to be revived by a doctor shortly afterward. These people get it good and many become ultra sensitive to everyone in the room around them. Simply touching people can reveal their future, though this does go away after a few weeks. I'm NOT saying jump in front of a car and you'll get ESP and you are an idiot to try getting it in this way. Furthermore, people who tend to get head injuries of any kind are way more likely to get Alzheimer's later in life.
Lastly people who live near heavy traffic areas, railways, and airports tend to get it too.
So how this works is, at night you usually dream the important events of your life. I don't know why, people just do. The trouble is when you are asleep, the parts of your brain that deal with long term memory are shut down. So you only have short term memory to go on and that's lasts a good 10 minutes or less after you wake up. So the idea here is to write down your dreams as soon as you wake up from them. The trouble here is dreams are about 20 minutes long and occur in REM sleep, which is every 90 minutes. So you actually have 4 or 6 dreams a night depending on how much sleep you're getting. There are methods to remember your dreams better such as focusing on remembering them before you go to bed. But it's far easier to set you alarm for 90 minutes ahead of time (give or take) so you wake up in the middle of the dream.
Understand though that there are 3 types of dreams. They are Planned, Lucid, and ESP.
Planned Dreams are when you dream about something you happen to be doing or watching within an hour of going to bed. This is why you have dreams of aliens after watching the X-Files before bed. You can use this to your advantage as you like. It's also why focusing on remembering your dreams before bed helps out.
Lucid Dreams are when you realize you are dreaming and start going with it. You can do anything you want because you are master of your own universe. Google Lucid Dreaming to find a whole society of people who do that constantly. You are asleep a third of your life so you might as well make the most of it. They also know better methods of remembering dreams and so on.
ESP Dreams along with showing you the events to come can also be used as learning tools. Combine with the other two types of dreams you can suddenly learn things such as the finer points of mountain climbing.
You may notice you don't understand your dreams at all. Dreams mostly lack logic as those parts of your brain that deal with it are shut down when sleeping. So what you're actually seeing is blatant content and hidden content. Seeing someone catch a crab can either be someone catching a crab, or you actually wishing they get Cancer and DIE! The zodiac sign for cancer is a crab. Writing your dreams down and drawing them as you saw them will help decode the messages. Things in color and in better focus tend to be more important while black and white images out of focus have less. Also throw away all Dream Dictionaries or books claiming to decode dreams. Dreams are made by your subconscious and meaning are unique to each person.
Scary things that support the existance of ESP.
Assuming ESP works the way I've written it out, it suggests that all humans have a collective consciousness. There are studies that support this.
Major disasters such as an Air Place crashing is a scary even that no one can predict... or can you? Strangely enough flights that crash have a higher rate of random people not showing up, arriving late, or changing their flight for odd reasons. This is in comparison to flights to the same location under similar conditions. The movie Final Destination is based on this study, of course Hollywood exaggerated the hell out of it by adding DEATH himself as the ultimate bad guy. When some of these people are tracked down they give some of the oddest reasons ever for missing their flight. "I had to get a cheese burger form down the road," "We felt like driving around the neighborhood for two hours," "My daughter wouldn't let me out the door."
Another odd study had people isolated in barren hotel rooms. None of them had any contact with the outside world or each other. It was almost complete isolation except for being fed and so on. They probably slept for most of the study in the end as there were no forms of entertainment around. At random each day one group was given a crossword puzzle from an English newspaper, supposedly the hardest in the world. The people who did the puzzle on Day 2 tended to finish faster then those on Day 1 (of people who they have equal IQ's with). Likewise the Day 3's beat the Day 2's and so on.
And it's not just humans, Laboratory mice made to run identical looking mazes on different days had the exact same results. Different Mice isolated form each other were selected at random to run the same maze design on different days. Mice that went later in the week tended to automatically know where the cheese was.
