As you sleep, NREM gets shorter and REM longer. After maybe 7-8 hours of sleep, almost all of the cycle is REM. NREM is very short.
When you remembered a dream at 3, it just means that that's also when you had REM.
BTW, are you talking about nap from noon to 3pm? If this was after a normal, full night of sleep, then your nap is almost all REM. It's because yur body knows this is extra sleep and it doesn't have to go through the deep, restorative sleep in NREM. It goes almost straight into REM. That's why naps are a prime time for a lucid, especially WILD.
