Once you're good and in the mood going to the biggest spirit Halloween you can find with no intent to purchase anything, just to test out their display animatronics can be really fun too but you need to already be willing to give in to whimsy or it just feels morosely corporate and empty.

If you live in a deciduous forest biome a good first step is a long nature walk to appreciate the changing colors of the leaves, followed up with hot apple cider with a bit of cinnamon mixed in, cozy on the couch watching your favorite horror movie and making your own Halloween decorations.
