Is this consider sleep walking ? ?

Lately when I sleep I have no recollection of when I wake up at certain hours of the night.

my roommate informs me that I do strange stuff.

like around the same time every night or morning like for say 3 in the morning. But I don't remember doing any of those things at all.

The thing is I think I was still sleeping but my body was fully awake and function as if I were awake.is that consider sleep walking.

But how do you call if youre not actually walking In this sleep walking.
