Very bright eyes, which seemed red in the lamplight, and sharp- looking teeth as white as snow.
while he was gone, the horse began to shack with fright. i could not see any reason for this as a howling had stopped.
Ruined castle, whose windows were dark and very unwelcomming.
I think this quote is gothic because it is impossible to have a red eyes and sharp teeth if the person is a human. So, if I look at the appearance of this man, it is similar to Dracula's appearance. if it is real Dracula, it will be supernatural phenomena.
i think this is Gothic because if the horse moved with fright, i think they might got ominous feeling for something unknown. also, i think it is baffling because there was no reason for wolves stoped howling.
if i hear word 'ruined' it also mean it is very old. So it can be much dangerous than other houses. also very unwelcomming window make people more apocalyptic and don't want to go inside.
