Good Animes for Halloween

Does anybody know any animes that are good for haloween? My friends are sleeping over and were gonna try and spook ourselves out, we have planned to watch: Hell Girl, Le portrait.....cossete (can't be bothered to type the name), Halloween special of the wallflower + any cool eps, the ghost episode in love hina and maybe the ghost ep in panyo panyo di gi charat.

And I want to know if there are any other ghostly animes like that, also don't suggest these: Hellsing, Vampire princess & nightwalker.
Also if the episodes are on youtube in english that would be good aswell because its short notice and I may not be able to hire them out.

Try Martin Mystery.

Elfen Lied might be a good one, but it's pretty disturbing so be warned.

Oooh, Halloweens past, but Ghost Hunt! It's probably one of the only horror anime around that doesn't rely on shock value to scare people.

Just remember: When you rent it, turn off all the lights to enjoy it to the fullest.
