Can some people really see ghosts?

I was out walking in the park over the weekend, spending time on myself. Some older lady whom I've haven't seen before (and there no real reason she would be lying) claimed there was a grey and white pitbull right next to me, following me everywhere. I didn't see anything.

The only grey and white pitbull I ever had was my old friend Cindy. She died from cancer, in my arms. I was then 4 and it was so heartbreaking to me that I had forgotten that memory for several years. Sweet girl.

Obviously I never physically saw her but seldomly dream of her, rare by now. Can some people really see ghost, even ghost of pets too?

There were time I felt protected. Like mentioned, I can't see her but it's like a positive vibe or something, like a warm presence.
