Liminal spaces in sci-fi are a goldmine for horror. The jump-point between stars, the moment of cryosleep, the interface between a brain and a machine. These transitional, in-between states where the rules are fuzzy are perfect for horror to seep in. What if something waits in the space between dimensions? What if you don't dream in cryosleep, but something else accesses your mind? The horror invades the process of transition itself, making movement, progress, or even consciousness unsafe. It traps characters in a permanent state of unstable becoming, which is psychologically corrosive and deeply frightening.
