Dude, you did EVERYTHING perfectly. This is one of the best LDs I've read in a while, and it's so simple. Simple, yet amazing.

Answer time!

1) Absolutely.

2)You can do that, but this was nothing of the sort.

3) I applaud your awareness! It's amazing to me how aware you really were. I need that kind of awareness.

4) You never lost it.

5) That depends on how your recall is right now. To me, it's always nice to keep up recall. Just in case.

6) Yes. REM cycles happen in 90 minute intervals. If my math is correct, 7:30 to 10:00 is indeed more than 90 minutes.
