If you've ever been stuck on a crowded train that suddenly, and unexpectedly stops in the middle of a tunnel, before the lights fail and the carriage descends into darkness, you'll know just how scary a place the tube can be sometimes.
Alternatively, just try and navigate Bank station at rush hour: also very scary.
But Brilliantly British have revealed that that's not the full extent of the terrifying treats in store on the London Underground: it turns out that a good number of the stations are, for reals, actually haunted, with ghosts and ghouls abounding since its creation in 1863. Check out the map below and then scroll down to read the stories behind each one.
