Sleeping feels random

I try to wake up at 6 am every day right So I go to sleep at about 9:30

Around 7:00 is when I start winding down listening to lofi dimming the screen, put on sleep mode screen, turn off all lights

And when I'm asleep I put on a 20 min video so if I'm still awake I can go do something else till I'm sleepy again

And yet still with all this sanctification I can only sleep without all the 2hr turn tossing 50% of the time

I also stay away from all the caffeine I can

Does anyone have any tips that I haven't done
