Ridley spent four years being groomed by Alec Underwood (who belongs to @macthedke) and he lived with him for a year. He also lived with Grayson for a little over two years. I say that to explain that he most frequently has nightmares about them. His dreams are often abstract and that extends to his nightmares. He hallucinates Alec and Grayson had lightning and thunder, so his nightmares frequently include thunderstorms. He also frequently has nightmares of being chased.

He does not usually remember his nightmares. It’s not always to his advantage though, to answer the last two questions together. Sometimes, if his nightmares are bad enough, he may wake up not fully connected to reality. He may think he’s a different age than he actually is, he may not know where he is, he may not recognize his surroundings. This doesn’t happen often, usually a product of his mental health doing particularly badly. When he’s having better days he still probably won’t remember his nightmares but will feel tired and groggy all day.
