Who could have been touching me?

I was outside one time, just sitting on the ground and looking at the clouds (it was drizzling a little) and I felt a hand on my leg, and a very comforting energy just washed over me. I asked my teacher (who is a nun) and she said it could've been God, an angel, or a dead loved one (my dad, my cousin, and my close friend). Who might have touched me on the leg when I was outside that day?
