Dream of father

I saw my dead father appear in my kitchen. He had a zombie look to his face. He was speaking sort of babbling and then he would laugh. He walked up to me and extended his hand out to me. I touched his hand, just at the fingertips. His fingers were wet He smiled at me and looked directly at me looking sort of embarrassed and he laughed. Then he stepped back to the corner again and started talking, but I couldn't understand the words. He would laugh and then say something again. Then he just disappeared.
