Lucid Dreaming

[iou]

Basically..

Go to bed, set the alarm for exactly 6 hours ahead.

GET UP when the alarm goes off, then get out of bed and do things, keep your brain active for exactly an hour.

Go back to bed, lie down and keep thinking of a place you'd like to dream about, and KEEP THINKING about it.

You will fall back asleep, and if you've managed to do it right you should start dreaming but be awake at the same time. Congratulations, you're lucid dreaming!

If you do manage to do it and unsure wether it's real or not, an easy reality check method is to picture yourself switching the light switch on and off in a room. Lights don't tend to work properly in lucid dreams and they won't come on.

That won't work for everyone, not saying most but some needs to have dream signs.
Dream signs are something that tells you "this is a dream, I've been to this before", they are gained by dreaming AND remembering them!
