I too, believe in ghosts and spirits and have had a couple of experiences to convince me , not seeing them perse, but on one occasion it was orbs, other times I have felt a presence.... also growing up across 3 cemetaries....my family on my my mom's side and a friend of my late Grandma have experienced things.
Owen: Whatever you believe, that is what matters and I hope your Mom's spirit is always close to you , as she embraced and loved you with all her heart during her earthly life .
I do believe in Dan's statement. It is possible .
