Sounds like the ghost might be trying to move to the light but ended up stuck in the tunnel for whatever reason, assuming their spirit box actually works and isn't just an RNG that displays random shit to amuse tourists. I dunno, personally I hope in my afterlife I finally get to cease to exist instead of becoming a ghost (that would be boring AF), being reincarnated again, put in a heaven where everything is so perfect I eventually get bored and ask for the previous option or even worse, get tortured in some hell for however long because my empathy burned out or something. It also may have called
@Cardboardtubeknight a hag, which is slightly disconcerting.
