What does putting baby down drowsy but awake exactly mean?

What does this look like? Does my baby have to have her eyes open? Or can they be closed while still sucking binky?
I know that's a dumb question but I'm so sleep deprived & desperate for help!

I've been doing this for weeks now but its nor working. Maybe I'm doing it wrong.

drowsy mesns in a peaceful state. eyes may be closing slowly. head bobbing from fslling asleep. etc.

Right before they fall asleep.
