im was wondering if any one knows any good party ideas for a birthday party and its all for supernateral so आप got any ideas

Dress up as your प्रिय character या monster (how creepy would it be to have a room full of women in white? xD), label your drinks as 'holy ...', like holy water, holy कोक and holy beer...

Score some cheap crucifix jewelry or... what are they called... rosaries, and hand them out to your guests to protect themselves from evil.

Make a devil's trap out of icing on the cake (look, I don't know, I'm making them up as I go along...)

Play classic rock, naturally!

आप could get all your guests to dress up as characters from the दिखाना then decorate the place where your having your party all spooky.... Hope this helps ;)

आप could do what DeanandSam said, that sounds cool. And if आप have some money आप could serve all your drinks in a सूपरनॅचुरल Cakehole travel mug and आप could have Jensen and Jared jump out of a cake but आप could also just make a boring old SPN cake ;)
There's plenty of things आप could do.
Happy birthday btw :)

आप COULD GET A CAKE THAT SAYS SUPER NATURAL AND PITCHES THAT SAY SUPER NATURAL

IF आप hit a party store,
pick up tombstones, skelton, for outdoor dec's,
hang meadowsweet (similar) above the door,
Silk screen t-shirts with the tatoo above the "heart"
या print off stickers of the tatoo to put on one's body,
Paint some of the Spell "markings" & hang them around the room (check out Hell House episode),
have a game of Jeopardy (or such) of जवाब of the दिखाना for which have to be answered in the form of a question,(with a prize of course),
make the tablecloth
(a black cloth, painted white/silver या gold? devil's trap)
that is used in the Seance episode of Pamela's,
could go on, but आप get the drift.
If this is too late, save for another time या just have a सूपरनॅचुरल party~
