am i crazy

once I saw my dog who was dead and he's a black and white Pekingese so I didn't know why he was standing there and then he was gone.I'm saying their're wondering what I just saw and something came to mind wait a minute is my dog trying to tell me he's still there.and so I see him again this time he's in the house I'm like what is going on here.and then he's gone again.and then I get this strange feeling someone sitting on my stomach because my dog always like to sit on my stomach when I was sleeping.and I look up and no one's there I'm like what is going on here and then it disappears I can breathe again.and you know what I finally say okay something's going on here I wonder if it's my dog.until then the next next day I hear a bark.and guess what no one's there.I couldn't believe what was going on.so then I feel something rubbing against my leg as if it's a furry dog.I know that my dog always like to like to rub against my leg because of course that's what he does.so was it my dog who is doing that to me or someone else?please tell me if i am crazy
