Right. I'm glad you said that. Strange, isn't it?
These things have happened throughout my life and, outside of my direct family, we don't usually talk about it. The connotations are so negative (and the church made it worse), but they did, and do, happen, and after Tony, who made me wait so long!, I decided I wasn't going to deny it. (It took me a while before I hit the Post button, to be honest).
Before my mom died, the doctors had given her up but she lasted another year, mostly because she loved Tony and she saw how it had devastated me, and was worried about her 'Benjamin', my sister came over from NY to be with her, and I was visiting, and she said to my mom at one point, "Don't you go haunting this place after you die, the new tenants have nothing to do with it!" My dear old mom, who I also miss so much and died a year after Tony, was pretty mean, miserable and bitter in her final years. (Love you, mom.)
I was so surprised at my sister, who never wanted anything to do with this kind of thing, to say something like that, that I confronted her with it. So you do believe, I said. "Well," she answered, dismissing it, "you know how she is!" My other sister, meanwhile, as she confessed to me afterwards, refused to have our mom die in her house because she was convinced she'd haunt it and she'd have to move out.
I researched it a bit, and it's actually quite common. All cultures and religions mention 'visits' from the soon to die, dying, and (recently) departed. Mostly to loved ones, family and especially spouses, but also to strangers. From three days to about 40+ is the average occurrence. However, the 'premonition dreams', like I have them, is less common and generally not looked on favorably.
But I just wanted to see Tony again, in any way possible, and he made me wait for 42 days!
