Venomous spider lurking in the corner of a haunted house

An horrifying image of a large deadly spider that is hiding in a corner of a wickely haunted house. The house has strange artifacts on shelves with skulls scattered around. The spider his spit his venom on a man and the man is in total agony as his body melts and liquifies and is just flowing on to the floor as the man disolves. Done in a dark and terrifying horror art style reminiscent of Bosch.
