Dream of woke up, eyes, grandfather, hugged, person

I was at an old train stain like from WWII. I was alone. There was no music. I kept wandering aimlessly. I looked up and saw a friend of mine who had passed away 2 weeks ago. He looked s solid as a regular person. His arms were out he voiced "Hug me!". I ran to hug him. As soon as I got near him he vanished. Faded away like smoke. It happened again and again. I started to get upset and confused. I looked behind me to see and old steam train. It was empty. I entered the train and sat down at a table with 2 chairs either side.A member of staff in a blue uniform came and gave me tea. The uniform looked like a blue jumpsuit. My friend joined me sitting across from me. This time he had a hospital gown on with a brown leather jacket over it. He asked me how I was. I replied " I'm okay. I just can't believe you're gone." To which he said, " I'm not really gone. I'm still here." He got up and went back out onto the platform. I followed behind him. He was in his regular clothes again.I saw across from us was his mum, sisters, and grandfather. They were all wearing black. Like they'd just gone to a funeral. His sisters had black mascara running down their faces.My friend went over and hugged them. His family just walked off the station like nothing had happened. Then his best friend showed up. They we interacting like he'd never passed. Skateboarding; joking around, etc. I went up to his friend and said "You know he's not really there right?" to which he said "I know but that doensn't mean we can't be happy for him." I woke up crying my eyes out. The dream was so real. It felt like I was really there.
