Hey,
thank you for the answer.
This is how I placed everything (
new placement), after much trying it's the only way I could figure out.
The only way the bed could be placed against a wall, is if I pointed it towards SE, my growth direction. I personally prefer the current direction, which is SUCCESS.
The original headboard is waaaaay too long, so I can't place it on the bed now. To replace it I've used the headboard from a smaller bed we had. It's not very aesthetic, but well, it should do the trick. This is how it's placed right now (
headboard).

The way the desk is placed, I can't see the entrance door, but I can see if somebody comes toward me just turning my head slightly to the right. Is that ok?
Btw, since I do my desk work in this room, I've two mineral water bottles around, should I remove them when going to sleep?
