My problem

So I lie down for an afternoon nap.
I usually have mental commentary going on, which I try to stop.
After about 1 minute of closed eyes, I see colours swirling into one point. Just repeating over and over.
A while later, I've either forgotten that I was trying to WILD and I'm drifting asleep, or I'm still lying there thinking "You're awake. You're going into a lucid dream," and I see more swirly colours.

What can I do? :(

Nailed my exact issue. I can see images/go into sleep paralysis, but I fall asleep or stay too conscious.
