Okay, from there, I would try to do a reality check everytime that these events happens:

- When the teacher calls the attention to another student.
- When while walking, you see someone else with a (choose color) shirt/jacket. Stick to the same color ALWAYS. Every single day.
- Whenever something odds happens at any game you play.

For the reality check, just check your hands and make sure you got your hand right. If this is odd at school, try to read something from your book/notes, and then look away and read it again to make sure it still says the same (assuming you could read it the first time and it made sense.)

The first two are common occurrences, and that will give you a lot of chances to RC. The last one is because electronics behave oddly in dreams, and even though you can get a glitch in a game, it is likely to happen especially asleep.

Good luck!
