Hey RioIsHere, last night I was reading Are You Dreaming? by Daniel Love and read something that might be of use to you. He has a method called FATE.

It is essentially where you set an alarm to wake up after at least 5-6 hours of sleep so you'll have increased REM at that point. Then over the next 90 minutes have an alarm go off at random intervals (you can use an app to do this. One I know of for Android is called Randomly Remind Me for Android). Set the alarm in your room so that you have to get up and walk to it. Also, cover the time with a cloth or something so you don't see the time.

Each time you get up and check the alarm, observe your surroundings and experience carefully and closely. Turn the alarm off and do a reality test (he recommends the nose-pinch RC). Once you know you're awake, return to bed. If you're dreaming, go about your false awakening!

If you're still awake, go back to bed and visualize the reality test as you're going back to sleep.

Next, you awaken to the random alarm and repeat the process of getting up, turning off the alarm, doing a reality check, and getting back in bed and visualizing until you reach your goal.

This could work, so long as your brother is okay with it or not in the room! Some people might find it a bit annoying so you could check with him beforehand.

Best of luck to you in having some false awakenings!
