Lucid prior to REM?

Lately I have been successful at using less time to become lucid during sleep. The lucid dreams start immediately after falling asleep. The dreams are not very clear or vivid as the imagery seems dark, but lately I have been having them before I should be in the REM stage. It’s a stage in sleep, where one normally feels they are falling off the bed, or entering sleep – sometimes waking up with a jolt; only instead, I’m in a lucid dream quite fast. Anyone else enter this stage quickly? I’m having fun exploring this new area of the dream experience :meditate:
