Where to go after killing the boss in the \"Border of Nightmare\" location? (Bloodborne)

In general, the situation is such that after killing the boss I absolutely don’t know exactly where to go, it happened in the location “Border of the Nightmare” I killed the “creature” there with 6 hands, can someone tell me where to go next? And there is still such a small moment I ended up in prison (which begins after a monster with a bag behind your back kills you), but faced with the complexity of the monsters, I decided to continue another location, but after the moment when I opened the spiritual village of Yaaargul, a teleport to this location became impossible, if anyone faced a similar problem, tell me how did you solve it?
