I would consider myself to follow mostly Pagan beliefs, but I do not label myself as or practice any one specific type of it's many branch religions. I am open to many beliefs. Wicca is a Pagan religion, and so I do follow some aspects of it, but I am not Wiccan. Most of my family members that follow these beliefs just say Pagan...or, some simply call us all witches, lol. Though I have family members who practice, we are all mostly solitary practitioners. I don't heavily practice, though, it's more just always there for me, a part of me. I do practice in small ways, though, when I feel the need to.
For me, basically, I follow a Pagan belief system in all of it's Earth following and practicing ways. It's all about nature for me.
For Halloween, I generally celebrate it as normal...but I do add in some Pagan traditions for both Halloween and Samhain. For example, like others above, I leave my Jack-o-Lanterns lit all night, if possible, on Halloween night. I light a candle for the dead, usually placed in a western window. I love to have small bonfires and if I can't have a fire, for some reason, I light many candles indoors. I always have fresh apples, apple baked treats, and/or apple ciders and drinks of some sort. Halloween night is a good time for spells and divination, too...some of my family members take advantage of this...I always want to, but never have much time. On Halloween night, after ToT is over, I love to just go outside in the quiet, breathe in the crisp night air and watch the moon while sitting amongst my lit Jack-o-Lanterns. You can just feel the magic and power in the air on Halloween night...
There are other small things I do, too, but mostly just the normal stuff like I wrote above.
