Can we learn things while we sleep?

I see videos on YouTube that are a few hours long and are meant to be listened to while sleeping to help learn the language.

Does watching these videos help do anything while sleeping?

It is pretty unlikely that you have the capability to learn while sleeping like that. It has been theorized that your brain spends your time sleeping to unpack the information from the day and store it, so it may not be able to learn additional information because it is already at capacity.

However, this is a subject of study and there are many of us that would like to be able to retain, process and internalize knowledge both faster and during periods of sleep.
