I find the whole concept sort of antithetical to good role play, because it's inflexible, unchangeable, committed in advance when we are in a position of ignorance about any significance, and (as the point has been made) very awkwardly superficial.

I haven't actually seen many of the dream scenes (just one) because I never used the illithid powers (as the game suggests we don't), so I'm not sure how it all plays out.

I feel like I'm not quite the player Larian thinks is playing their game. But that's ok, I still enjoy the combat.
