It was my sophomore or junior year, a few months after my great grandmother died, I woke up at about 2:30 in the morning after having a nightmare, I am not sure what the dream was about, but it seemed very real. I woke up and heard a lady’s voice saying “Hello? Hello? Andrew, are you there?” I am not sure if I was still dreaming or not, but I think that I really heard it because it scared me a lot. I kept waking up at about that same time for about a week as well.
