Have you guys ever been in a half dream/reality state?

Idk if this is a thing or not but usually after I wake up and I'm still really sleepy my mind goes into this half dream/reality state like I know I'm awake but I'll hear a knock on the door or a voice and it seems and sounds so real that I have to question myself on if I really heard it. I don't know if I sound crazy lol but yeah it only happens after I wake up. It isn't like a day dream or like I'm creating the sounds it seems like reality but you just kind of know it isn't? I don't think I've ever had a visual experience of this it's always been sounds. What do you guys think about this? Have you ever had a similar experience?

It sounds like a form of hypnagogia or sleep paralysis to me. I haven't heard sounds but sometimes I will halfway wake up and think I feel my body and try to move it but can't or am slow. Then I wake up for real and my room and perception is different from before. I've read many posts here where people describe sounds though.

Well just yesterday I kind of did - I was so sleep deprived, sometimes I would be like, "WTF? How did I get here? What am I even doing right now?"
