My Father's Ghostly Visit

Last night around 2 a.m., I woke up. Why, I don't know. I kept telling my dog to lay down as she was up all night. Then I heard my phone ring. I went down stairs and I closed my phone. As I walked upstairs, I saw this man. He was very tall and wearing very old clothes. He was just standing there in my hallway. I said, "Oh." I called my husband and asked him why are you in the hallway. He said, "I'm not. What are talking about?" So I looked again and said excuse me. He moved out of the way and I went back to bed.

That morning my husband came downstairs for coffee and asked me why I took down all the pictures and put them face down on our dresser. I told I didn't do that. I went upstairs to look and the pictures were face down in a straight line and maybe about 2 or 3 facing up and the only picture still up was my father who passed away 20 years ago.

What do you think? I don't know what to think about this. Is he telling me something with the pictures or does he want me to know that he was there? I know he was real and I wasn't dreaming it. My dog was up all night and I know she felt something and the pictures? What is he trying to tell me? I would love to see him again maybe this time he will tell me why he came and if he needs something?
