What signs do we see in the text that destination is a frightening one on this particular night of the year

Brown is well aware that journeying into the forest this night is a sinful act. None-the-less, he is shocked to see how many people have followed the same path.

"Dearest eart," whispered she, softly and rather sadly, when her lips were close to his ear, "pr'y thee, put off your journey until sunrise, and sleep in your own bed to-night. A lone woman is troubled with such dreams and such thoughts, that she's afeard of herself, sometimes. Pray, tarry with me this night, dear husband, of all nights in the year!"

"Amen!" cried Goodman Brown. "Say thy prayers, dear Faith, and go to bed at dusk, and no harm will come to thee."

With this excellent resolve for the future, Goodman Brown felt himself justified in making more haste on his present evil purpose. He had taken a dreary road, darkened by all the gloomiest trees of the forest, which barely stood aside to let the narrow path creep through, and closed immediately behind. It was all as lonely as could be; and there is this peculiarity in such a solitude, that the traveller knows not who may be concealed by the innumerable trunks and the thick boughs overhead; so that, with lonely footsteps, he may yet be passing through an unseen multitude.
