So i started using the CS today for Morrowind, i've already worked on the CK for Skyrim, so it was easy to get into this one. especially since its less advanced, i've done two quests for now and both worked out great. talk to an npc, steal something or kill someone/report back to the NPC. basic stuff. however now i'd like to try something new, i want to start a quest where an npc attacks me while sleeping, kind of like how tribunal starts. however i want the attacker to appear only when i sleep in a specific bed or cell. would something like that be easy to do? what are the steps?

Yep, just put a script on the bed that is activated when you use it, and have it spawn your minions.

I think you know this, but create a unique FORMID for the bed so this does not happen in every bed in the game.
