I see आप पोस्टेड this a साल पूर्व so I don’t know if आप still need ideas या not but…
संगीत – Every party needs music. I recommend making a mix of your प्रिय हैलोवीन songs for your party.
Drinks – Believe it या not, I recommend Kool-aid. अंगूर and चेरी mixed together look like blood and it tastes good.
Snacks – हैलोवीन cookies, cupcakes, and candy.
Gift bags – Get some हैलोवीन stickers and a few other cheep party favors. Put them in a small paper bag.
Decorations – हैलोवीन balloons, pumpkins (real of fake), and whatever हैलोवीन decorations आप think are cool. I think something with a motion sensor would be cool right inside the door, so guests set it off when they come in. If आप live near a party store, see if आप can find हैलोवीन paper plates, napkins, and cups. If आप have a dimmer switch, dim the lights. If not, try using electric candles and/or light up decorations to light up your party. I don’t recommend using real candles in case someone knocks them over.
Entertainment – Horror फिल्में are always good. If आप have room, a spooky scavenger hunt could be fun. A costume contest is a good idea. Give a prize (something spooky and cool) to the person who wears the best costume. आप can have set judges या have your guests vote for the winner. आप could carve Jack-o-lanterns if आप don’t have too many guests. Of course ghost stories are fun.
I’ve never been to a party so आप might not want to take my suggestions seriously.
