I mean, at least in Otherspace you might catch a glimpse of some stars or nebulae that are a different colour to grey... can you see anything apart from the blue stuff when in hyperspace?
Lets just say you don't wanna be trapped in hyperspace in Legends , you can get Hyper-Rapture, or if your force sensitive you can get hunted by a Starweird which will drain you life essence.
Probably hyperspace you can get ill from it but being trapped all alone in other space just seems dreadfully depressing. Also If I'm trapped in hyperspace there is a possibility I can time travel to either the past or the future.
