I've done Henantier's Dreamworld, usually by hopping up (after a bit of trial and error) on one of the braces and shooting the minotors from safety. The hardest time I had was with my knight, otherwise my characters do the jump thing and all have at least that much acrobatics, Well this quest is dull now after a lot of play through, but I was surprised to see companion Vilja there. I reloaded and gave her my gear, told her to stay with Henantier till Test of Resolve, then we went in and just killed the beasts. I gave her back my things because I worried they would be scripted disabled. I was not able to take Mysterious Scroll by giving that to her though, and it took an extra try since at one point I told her to wait before some traps and realized she would not automatically join me then.

Vilja is fun for me in an odd way, very interactive, and I seem to be playing Vilja's Oblivion, atm.
