I agree with Dragon on this. If anything, aside from Chrysi, my other major waifu that has stuck is Aisha Clan-Clan from Outlaw Star.
Aisha, huh? Go figure. Closest character I've had to one would probably be Patchouli Knowledge, and even then I stopped when she began turning up in my dreams for no real reason.
I don't think Aisha, nor Chrysalis, have been in any dreams. At least with the latter I can say for sure.
That's one wish I'd rather not see fulfilled, thank you. A lot of fictional characters I've obsessed over to some degree from college onward have turned up in my dreams at some point. Patchouli, Alice Margatroid, Washu Hakubi, Hellmaster Phibrizzo... I can't clearly recall whether Aisha or Vinyl Scratch have made appearances, though.
I don't recall any fictional characters showing up in my dreams. Have I ever showed up in your dreams? Not that I recall
I had a dream that I accidentally ran over Fluttershy's bike in a parking lot. I tried to apologize but she started crying and beating my hood with the handlebars.
