Spirits

Does anyone believe life after this one?

I swear I sometimes know/see loved ones. I have had my MIL's Dad talk to me, say things only her or her family would understand. I keep seeing a guy who used to live in my road, who died about 20 years ago. I saw my Granddad's Nanny. She died when my Granddad was 2 so that was 1936. I described her and then we got a picture of her. Every now and again, I get the feeling pulling an bottom of my top even when I'm in bed.
