Haziq, first, this should have been posted in the furniture section. It's there just for this type of request. Please familiarize yourself with this forum structure. Hopefully Colin (or another admin?) will see this and move it for you.
I think I can make what you're looking for. The "pop-up ghost" is a good idea for a jump scare. I would recommend a two-block or bigger furniture piece for that. A simple tray and a syringe is just that - simple. I can put some implements on the tray and can try to make them look bloody, too. Do you want medicine like bottles or a shelf with such items on it? As far as surgeon tools, I need something to give me ideas of what you're looking for. If you can find images of some examples, that would help.
I'll need more info to get started. Images of the equipment you'd like and even an idea of what you want the ghost to look like. I've made a people pack and might use that as a base to make zombie looking people or a skeleton looking body or a white ghost...
I may not be able to start immediately but I'm addicted to furniture and I always love a challenge. I'm just a little busy IRL right now.
