Before going to sleep, think of three good things that have happened today.
It takes practice, but it's supposedly possible to bring things into your dreams and even control what happens.
If you manage to change your dreams, props to you. If you just manage to get yourself into a better frame of mind before you sleep, its still worth it.
Don't forget to write your dreams down in the morning before you wake up properly, or you won't be able to remember if it worked or not.
