It’s absolutely possible to feel an instant connection with someone you’ve just met. If you do feel this way, you might have met somebody from a past life. This person could have meant something important to you in the past, such as a lover, a family member, or a best friend.
It’s also possible that the two of you parted ways prematurely, for one reason or another, due to an unexpected death, divorce, or breakup. Perhaps this is their way of reconnecting with you to reestablish the strong bond the two of you shared.
