I agree that people can have the same idea unconnected, but I do think there is some sort of connection/energy between people—between any life!
I’ll give one example: My mom. Every since she was little, she’s had this weird ability to know when something’s going wrong with someone in her family. She was at home one day as a kid and had this really weird feeling midafternoon (2ish), so started calling the people she could (mind you, this is pre-cellphone) asking if her brother was alright, what happened to him. She didn’t hear anything until that night when she got in contact with him and people that knew what happened, his car had been hit around 2, everyone wanted to know how she found out something had happened, but she hadn’t, she was home alone without any notice… true story!
She told me that story after picking me up from a sleepover one time when I was younger. She asked how it went, and I told her good! That I had a lot of fun… (truth was, halfway through, around midnight, I wanted to go home really badly, because I only knew the birthday girl, not the others, and was kind of being ignored… but I didn’t tell her that, because the next morning was better.) She was like, ‘oh, because around 12 at night I jumped awake, sure you were unhappy. I almost called your cell to ask if you wanted to come home.’ And then I told her I had wanted to… it was creepy, but incredible!
Hm… it doesn’t sound as amazing just written down. She’s had other instances like that, and I don’t believe she’s the only one to have weird unexplained feelings. Not so much we’re psychic, but that yes, somehow, I think there’s a connection none of us can really explain, understand, or even consciously know, that we share with each other.
