It's Halloween on Monday and we want to know how you're celebrating the spook-tacular event.
It's the time of year for scary costumes, ghoulish parties, and eating sweets after trick or treating.
Halloween can be traced back to a Celtic festival called Samhain, originally a way to scare away ghosts and ghouls that might come to Earth.
It was believed the barrier between our world and the spirit world was at its thinnest.
The festival survives to this day and we asked you how you're celebrating Halloween.
I'm dressing up as a ghost but I'm not sure what my little brother is dressing up as. HAPPY HALLOWEEN!!

My family decorated our house for Halloween. I'm also dressing up as Marty Mcfly from Back to the Future, one of my favourite films.
This year I am dressing up as a evil prom queen and my little sister is dressing up in my old witch costume.
