So I woke up in a sleep paralysis state (Awake with eyes closed, but unable to move or speak) and I hear a voice asking me: "Are you squealing yet?" It kept asking it over and over and it sounded as clear as day, the freaky part is no one was in my room or home at the time and the only other thing I could hear alongside the voice was the birds that usually chirp during the morning. Should I be worried for my sanity or is this common with sleep paralysis?
