Different kind of connection

Hey yall, have you ever had such intense connection with someone? Like you could LITERALLY feel the energies merge and you get very strong feeling of love overwhelming you. It happend to me once and I couldnt find much bout it on web, can someone explain that. and i wasnt even on drugs or anything. And we both felt it, very often we had like moments of wierd magic stuff going on but this was the only time that we connected on that kind of level.
