We used to do this every year when I was a kid. I think it's time to revive an old tradition.
Carve three Jack O' Lanterns. Each one should have a different face. They can be a happy face, a sad face, a peaceful face, an angry face, a scary face, and so on.
Place the three lighted pumpkins facing you in a semicircle. In the dark, begin to gaze at the faces. Ask that you may be shown in the flame something that in the past that will guide you in the present. relax and half-close your eyes, blinking when necessary.
You may see in the faces your beloved family members that have passed. You may sense their presence and feel a gentle wind or see a picture in your minds eye from the past. Nothing can harm you here. For you are merely connecting to family love that never dies.
Close you eyes and meditate on each face. Listen for the voices of your ancestors. This is the night of the year when it is easiest to make contact with the past dimensions and encounter those that can guide you to wise choices in the future. What you may encounter is your own evolved soul that can access the wisdom of other times and places.
When you are ready to end the experience, thank whomever you visited with. "Go in peace. May you be blessed on your own paths of wisdom." Burn some sage incense.
Name each ancestor who comes to mind and say " May they be blessed and protected." Don't forget to include yourself. If you still harbor resentments with anyone who has come forward, you may ask for forgiveness and to forgive at this time.
Smudge the room and yourself. Take the Jack O'Lanterns and place them in windows, letting the candles burn out.
