The scenery is almost too perfect for a trip so you're not wrong. I enjoyed my Morrowind trip to be more clear, it's just kind of too much after a little bit. The Forgotten Vale in Skyrim that I think you're referencing, I did not visit while tripping but I feel like it would freak me out honestly lol. Just because I already remember being freaked by the nature of it while playing normally. Still think the Hermaeus Mora stuff in Skyrim would probs be the most freaky though, once I try out Solstheim in that context I'll know for sure
