Does anyone have some tips on how to keep my eyes closed while waking up? I appreciate any help i get

About 3 days ago i woke up in the middle of the night and i kept my eyes closed.
Just a few seconds later i saw a whole dreamlandscape building up and i could get right into it. This WILD lucid dream was very vivid and it was so easy to get in.

I tried to do that again last night but i just couldn't keep my eyes closed as i woke up. I didn't want to wake me up with my alarm clock because that would mess it up...
So i tried autosuggestion with the sentence "i will wake up after every REM cycle and let my eyes closed". I even woke up 4 times this night but i couldn't my eyes closed.

Is it ok to wake up after the REM cycles or should i try to wake me up during a dream somehow?
And is there a specific trick not to open my eyes when i wake up?

Thanks for the help
