If you're looking for something meaningful to do for Samhain, here's a suggestion:
Any evening over the next few nights (end of October/beginning of November), sit in a comfortable spot in your house, turn out the lights, light a few candles, and pour two glasses of wine.
Then sit quietly and think about a loved one who has passed away, either in the past year or previous years. You can even just speak out loud to them as if they were sharing the wine with you. They will come to you in that moment, so just allow them to be there and take comfort in it.
When you're done, finish your wine, but take their glass and pour it out onto the ground outside. If you can, leave the glass outside with a candle burning nearby (then pour the wine out in the morning). That way, the spirit of your loved one will be able to find you easily.
