Please imagine that Jim for whatever reason needs Spock in the middle of when he knows Spock would be sleeping and Jim busts in screaming and turning on lights only to scare Spock AND Bones out of their skins. Bones literally LEAPS, screeches in primal fear, and accidentally punts Spock off the bed (where he falls super inelegantly, flailing and grasping at the nightstand).
imagine bones not being able to see anything, as the room went from pitch-black to super bright
imagine bones being one of those people who sleeps with a weapon under their bed
imagine bones pulling out a baseball bat and charging, still clad in only boxers
imagine jim screaming and racing out of the room, bones right behind him
spock falls back asleep on the floor
