Memories of Medusa.
It's weird how, in dreams, something completely out of left field can happen, but you have dream-memories that give it context.
In my dream, I was walking with Ms. NameRedacted, who was my girlfriend years ago, and she said, "Oh, by the way, I was talking to Medusa and I guess she looked in on you the other night; she says she's figured out a way to stop you from snoring without even coming into your house; she just slams the car door outside." and then I woke up. But that's not really the interesting or weird part.
And, in the dream, I actually remembered Medusa: Nice lady, actually very pretty if you can get over that her hair, and her body below the waist, is all snakey. Apparently the 'turn to stone' thing was only if you saw her in person, and I'd only ever seen her in second-sight. She'd been assigned as my psychopomp years before. I'd met her when I was seventeen and crashed a truck. She had showed up to ask if I wanted out of there, and I said, thanks, but no, I think I can handle it. Since then she'd been coming by to chat every so often, because she didn't meet very many people who didn't freak out when they saw her and thought I was kind of nice. She said she and Eurayle had both taken up psychopomping since Zeus got overthrown, but I never met Eurayle. And after I declined her offer with the truck thing, she hadn't been reassigned as my psychopomp again - that was up to Persephone now. I had never met Persephone either.
In response to the news that she'd looked in and hadn't woken me up to chat, but just slammed a car door to stop my snoring, I was a bit disappointed, because I'd like to have seen her again. Not, you know, in her professional capacity, but just coming by for another visit. And I didn't have to worry about her in her professional capacity any more, because I'd been reassigned. I was even a bit worried for her, because slamming a car door sounds like something somebody does when they're angry or frustrated, and I hoped she was all right.
So, all these memories, of things that never happened, and a person/monster/spirit/whatever that I haven't actually ever known, whirled around in my head when my companion mentioned that she had been by to see me but I'd been asleep at the time.
And then I woke up, with all these bogus memories still kicking around in my head.
