In the night the player was begin chase by a black flog. And the player had to find out about what the dream meant. But the dream was really a cry for help. By a ghostly spirt.
You can edit your posts. otherwise your SPAMING and that kills kittys. and way, would the player act out the dream or would it be a seane or would it show up in the journal?
Well having a stylish dream would require someone making a cutscene and that requires a lot of work. This is rather epic as well, but I like the idea. I would like to see it as a part of Main Quest.
Anyway, feel free to develop this idea if you have other plans.
The player actually experiencing the dream multiple nights would be a tad hard to get right, but easily done and accomplishing the purpose with "dreams" like the PC character had about Dagoth Ur, but that hint you in a direction of the aforementioned cry for help from a spirit, other than being just a nice little message.

I agree that it would be a fun quest but would require a ton of work so if you know someone that has time to make a bunch of movies for it then go for it otherwise you may want to try an easier to do quest.
