What if you think you are dreaming?

Answer 1

Then you should do a reality check! If you are really lucky, and you are dreaming, then you might become lucid. To do a reality check:

One method is to count your fingers. This can be frustrating because when you look at your hand in a dream you may have a thousand fingers, but it will look perfectly normal to you, as if that is how it has always been. Nevertheless, count them.

Another method is to jump. If you fly, you are dreaming.

You could also lean on a wall. If you fall through, you are dreaming.

You can check for consistency. If you look at a clock, look away, and look back to see it is a drastically different time than before, you are dreaming. Try combining these, and more, to be more effective.
