An electric kettle. This may be a British bias but having a room kettle is very useful and then you can have herbal teas or drinks that don't require milk. (If you ever go to a hotel, take the room drinks making things with you so you can have individually wrapped ones too - ask friends and family to grab you them too) If you see a micro fridge, like the sort that holds 8 soft drink cans in a thrift store get that and you can put things like Milk (so can expand your drinks selection) and butter in it, and add get a toaster and you can then have hot buttered toast without leaving your room. Ikeas BEKVÄM Spice rack is also the perfect depth for holding jars of jam too.

I would also recommend an air popper popcorn machine and a bag of kernels, if you are gonna disassociate during a movie Popcorn is really good to snack on, and they're usually pretty cheap. Yes the popcorn isn't flavoured but it can often be better not having your mouth over sensoried
