A long while back I was hanging out with one of my sisters and she said that she hears thunder in her head when she gets startled.
Me: "Scuse me. What?"
Her: "You know. That thunder you hear when someone startles you."
Me: "Again. What?"
Her: "You don't hear thunder when someone startles you?"
Me: "Uh, no."
Her: "Oh. I thought that happened to everybody."
Is this a thing? Does this happen to anybody else out there? She did struggle with depression for much of her life. Could that have had something to do with it?
I hear/get something of a sound or a feeling when I'm startled or am at the edge of falling asleep sometimes. I don't know how to describe it but this seems to be the same as what your sister gets
Jeezus, I've never had the experience of hearing someone screaming at me on the edge of sleep. That sounds horrifying! For me, it's always like she's calling to me from another room, like "Honey can you come here?"
