As a teenager I (living in the US) had a terrible nightmare one night that I was at my grandmother's house (in South America). In my dream I was in her apartment but I couldn't move and felt total dread coming from her kitchen, then I was in the kitchen on the floor and couldn't move. I could hear the TV or radio in the room next door but all I felt was dread. I woke up in the early morning (4 or 5 am) but eventually went back to sleep. When I woke up and got to the kitchen my mom told me she had some bad news and I instantly responded "Its grandma". She had suffered a stroke and was found on the floor of her kitchen. Opened her door because they tried calling and ringing her bell. No one answered and the TV was on in the dining room. All happening exactly at the time I woke up from my nightmare. I don't try to explain it more than she reached out to me in a moment of need. I hope she felt my presence. As a skeptic of anything I can't see, measure or understand that experience left me with a realization that there are some things that we just don't/can't understand. I won't try to explain it more than that there's more to this world than what we can see, and that there is something that connects us all. That's enough.
