If you have a feeling for someone whether it is bad or good and you don't really mean it what does that mean?

I think there are so many factors which work behind it, like the person's "ORA", our relation with that person in pichle janam, effect of the person's behaviour on us. we don't know but our unconscious mind is continuously working, whenever we see or meet any person, he or she leaves some effect on us, it can be good or bad and our unconscious mind makes a image or memory of that person. whenever we see, meet or think about that person, our unconscious mind start 2 send signals of how it experienced last time, and we feel either good or bad about that person. It is all what i think, it may differ from person to person.

Thanks
