Is it correct to say the following?
1) We take a blanket while sleeping.
2) We cover ourself with a blanket while sleeping.
1. No. You could only take a blanket while you're asleep if you're sleepwalking.
2. If, while you are asleep, you pull a blanket over yourself, yes.
I think what you're trying to say is "We sleep under a blanket".
