One out of every seven people are affected by sleep drunkenness due to a separate sleep condition, mental health disorder, or medication.
I am the sleep drunkest person ever. I am a sleep lush. This morning, my alarm clock went off, loudly and about 2 feet away from my head, for seven whole minutes before I realized what it was. I remember thinking, groggily and maybe still half dreaming, “Oh my god, that is so annoying, I wish someone would turn it off!!!” And then I was like, “Wait, I can turn it off!”
Also, one time I woke up and hallucinated in the dim light that there was a giant spider on my bed. It was the only time I have seen an illusion like that — it was so vivid. I grabbed a tissue and tried to smash the spider multiple times and was so confused when no bug guts appeared on the tissue. So, either I was sleep drunk or my apartment is haunted by ghost spiders.
