Meh, maybe, but I don't think so because all that 2 hours I never lost consciousness. There was no point in which my memory was "black". I was talking to my roommates, told them I'm going to bed, took Ambien, lied on my bed and suddenly started to feel very confused, forgetful and it "felt" like I'm somewhere else. It wasn't a very visual experience (like psychedelics) but it felt like I was so confused that I wasn't able to comprehend where I am.
