knowing someone before

Hey all,

I read up a lot on signs of knowing someone from a past life. Many sources say you have an instant reaction or connection with them. Even though i believe many people, even random strangers may have shared lives with us in the past, I am wondering if when meeting someone initially doesn't trigger any past life memory or pull, but down the line one suddenly forms. Like no instant connection or reaction, but one develops.

What are your thoughts?? I ask because someone has popped inro my life who i now feel jittery around with no known reason except for the fact that I find a need to dig in past lives regarding this person. This feeling was not instant, but developed randomly a couple months later. Just a feeling like i need to take care of something regarding it.

What are your thoughts on this topic??
