I experienced a knowing about my future husband on our first date. Then later that night I had an out-of-body experience where I saw our future.
I was filling a glass of water and, in the middle of filling the glass, I found myself in a different room. I was everywhere, in the air. I was using hearing and was able to feel emotions. I could hear and feel my boyfriend who was then my husband and we were all at the table talking and laughing. It was my husband, myself and our two children. I didn't see anything. I could hear the laughter and feel a wonderful loving cohesive family. I couldn't see or hear what was being talked about but I knew there was conversation and joy. It was like I was in the room, but not floating above, but everywhere. I didn't have a body.
When I came back to my glass being filled by the faucet, it wasn't any fuller than when I left, even though I felt like I was gone for a long time. It was very emotionally deeply joyful, and I couldn't talk about it without getting emotional, and I didn't tell anyone for at least 6 months because it was so hard to talk about.
On the first date, after I talked to him for a very short period of time, I absolutely knew that I traveled with him through many lifetimes. All of the information was just there. I knew that we had made a plan to meet, and I felt a bit of annoyance because it felt like he showed up late, but I absolutely knew that I would marry him and that I had known him for forever. Many lifetimes. I didn't know him physically but I definitely knew his soul. I knew it was a glimpse of the future and it became reality in future years.
Prior to this I did not believe in reincarnation and actually never really thought about reincarnation. After this experience I knew it was a reality.
