I like the Hypnogirl files here by Hypnofemme. Most of them are free.
Fiona Clearwater has two Patron-only files that help you experience what you see when you watch porn. The latest one is here:

She might have a few other files that are also suitable. It's just $6/month and you do get to keep the files you have downloaded, so it's really inexpensive to try.
