Someone said before you had to do a reality check like every 40 minutes while your awake to remeber to do it every time you dream. I don't think anyone does it that often but my point is you need all the help you can get in remebering to check. I didn't use anything before and I would only remeber for like 3 or 4 hours at night and forget to check any other time during the day.

It did work then but not really often so I stopped untill I can think of a better way to do it.
