yeah, it turns out it's not ...uncommon, exactly. Mention it in a group and you'll often get one person who goes 'oh, hang on, *that*?'

Everyone's heard of alien abduction/succubus/black hag, but since it's not often that said 'victims' ever break down the experience properly and tend to add a whole bunch of fantasising over the top, the people who aren't attention seekers tend not to tell anyone else, having dismissed it as bad dreams once they properly woke up. (the program I watched also went through the personality type of the ones who insisted they'd been abducted. A bit lonely, intelligent, often not quite social, and a whole heap of attention seeking.)
