just out of curiosity, how much later do you guys take a nap in the day compared to when you initially woke up in the morning. i've tried naps a few times, but most of the time i don't remember a dream at all. but when i do they are always extremely vivid and often lucid. i'm wondering because i wonder if there's a point in the day where if you take a nap you must get past the initial 90 minutes of sleep to dream. cause sometimes i've napped for an hour or so and had no recollection of anything...
