Mine works a bit different but a lot of the aspects are the same. Some details:
You can choose what you are wearing while you are sleeping. Sorry, no armor possible only normal clothing, ever tried to sleep in armor? I did and there is no way to get good sleep in it. You also can choose to take a small weapon while sleeping but then you have to sleep nak.. in your patented glued Vault Tec underwear.
The 'Sleep' dialogue box appears and let you choose how long you plan to sleep. You could say you adjust a alarm clock
. Then your character goes to bed and maybe something happens while you are sleeping or maybe not
(dreams, visits, .. see the rest of this thread) . Maybe you wakeup or maybe... you know what I mean here.
If your sleep is disturbed it depends on your agility and a little randomness how fast you get out of bed and dressed.
It is possible to get murdered while sleeping but this is pretty rare and if autosave is enabled there is a save to go back to as you get in bed.
You can change the camera while sleeping but 1st person shows you yourself (sorry I don't want to make a extra animation for this, normaly your eyes should be closed in 1st person).
The first version with 6 different encounters is ready for the normal game. I am working on the FWE compatibility right now. If this is done I make a beta release.
Btw. I achieved all this completly without FOSE. So it will not be needed.
