Am I really seeing ghosts?

Ok so it was like 8:30 one morning when I went out in the porch of my appartement to get my shoes on to go to school, as I was bent over I saw from the corner of my eyes an old man who was wearing a white shirt and a white pair of pants he had greyish white beard and hair, but I only saw him for a few seconds and when I turned around he was gone. I described him to my mother and my father and they both said that the way I described him looked just like my grandfather who past away when I was about 5 years old. Did I really see my grandfather or am I just going crazy?

Well my opinion is that u did Becuse I see ghost all the time

You Might Of Have . Just For The Fact He's Your Grandpa . You Shouldn't Consider Him As A Ghost . Maybe An Angel ? Probably Just Wanted To Check On You .

nope it sounds normal he prob wants to check up on you, or let you know that hes ok, in the spirit world and not suffering
