I think the dream gallery is more for one-time events because most things are repeatable in the game. It could change in the future to include everything. The devs did seem to cover their bases with the one off scenes in the gallery and since the NTR stuff has the potential to be snubbed out and lost through future choices, I think that's why it made its way into the gallery already.
Try dreaming two or three nights in a row. I seem to recall the gallery needing an extra day or so to update properly. If that doesn't work then I don't know what the issue is. If you're wondering about all the dark character spots, its because those characters don't have content yet. Hope that helps.
It didn't work the Gallery remained unchanged
Maybe it's just me being biased as I like athletic girls, but as she has one of the more normal faces that doesn't contort horrifically then I'd imagine a lot of folks do... Adel though, not sure if anyone would choose that gremlin as their favourite.
You have to go to Claire's apartment right after you send her in a taxi to see all the NTR stuff. I thought it would play automatically, but you send her in the taxi, see the beginning of the taxi event, the hour changes and then you manually head over to her apartment to see the last half of the taxi event. That messed me up at first as well.
The sixth image scares me more.
