I never sleeped by a grave before. It's surprising warm and very inviting.
It's a really life changing bond that you can have we your passed ones.. Some I didn't know passed have visited me at the festival and in a dream like state. Then I heard voices, singing of a child and their dad.. It was our voices.
My dad use to sing me songs to help with my insomnia for years...
All I can say is, that was the best sleep of my life.
