When is the best time to go to sleep in order to have the best recall and chances to have MILDs (the one where you do RCs in the dream)?

-Should I go to sleep not very tired?

-Should I go to sleep so tired, I might pass out?

-Or just have a nap in the afternoon?

I've noticed that when I go to bed super tired and wake up after a dream, I'm too tired to want to write it down...
