I can't tell you how many people say they are srtessed out and all of them are having trouble with lucidity. So don't get to discouraged. As soon as the SATs are over maybe you can settle down a little.

Reality checks. All I have to say about them is.....Keep them real!
Meaning make sure each one really really COUNTS!
By doing so many per day you may have started to make them habitual. As a result your brain does what you had explained in your dream. It discounts it.
Three reality checks done with conviction and Thoroughness is better than 25 that you do just going through the motions.
With each one make it complete and be meticulous. Prove to yourself you are not dreaming.
If you make everyone count and all-inclusive then in your dream when the time arises you will know doubt be able to account for consciouness.
