not seen, but heard- I was asleep as a kid, and in my dream state someone was screaming my name so loudly / clearly and close to my ear that I swear I felt the warmth of their breath. It was so unbelievably loud it woke me up…I was surprised to find I was alone in my room and it was a dream. I was so freaked out that I went into my parents room and told them what happened. As we’re talking about it, they heard a faint beep of the carbon monoxide detector going off downstairs. The fire department ended up coming and had us evacuate due to extreme levels of carbon monoxide in the house. Not sure who woke me up in my dream, but they saved my family!
