Fairies do exist, I found that out one night unwittingly when I woke up and seen a puff of smoke above my bed, it turned into a web and then something that looked like a cross between a grasshopper and butterfly. After getting scared and turning on the lights, I regained my courage and turned em off again. This time I figured out how to see them at will, here is how:
1) Sit on your bed in the total darkness, or as close to it as possible.
2) Focus on a point to your left, just above eye level.
3) Once focused, concentrate and block all other thoughts out of your mind.
4) Within a minute or two, maybe less, you will start to see what looks like a "thread" streaming down in the air at a 45 degree angle downward southeast.
5) Continue to focus on the "thread", it will star to grow thicker and thicker until it looks like mini spider web.
6) Shortly thereafter you will see something at the end of the thread. It should look greenish in color, watch it as it descends. At the point where it meets your bed, you will see what looks a strange kind of insect. It will look like a cross between a grasshopper and butterfly. Watch it as it crawls on your bed.
7) Its impossible to touch, your hand will wave right through it! This is because these entities live on the edge of our living plane and the "other side". They go back and forth between the two.

Important: DO NOT TRY TO CATCH THEM, OR PHOTOGRAPH THEM! This will piss them off, and negative consequences may occur. Trust me on this one!
