My mother saw my father after he died...he came to her bedside. And my grandmother before she died said “who is that man in white?”....someone she saw who no one else saw.
I think my mother warned me a few years ago...I was sick and should have gone to the doctor...not doing so almost killed me. I also feel that I’ve had messages and warnings at important times. And...once...a long time ago I saw something in a “dream” very specific that hadn’t yet happened - it happened 3 weeks later.
I’ve never had anyone I’ve lost including my spouse, mother & younger brother ever contact me in any way. Kinda wish they had.
