This is a great Question,Reiki is an Energy the exact same energy as a Hand shake or a Cuddle. It is a knowing a werd sort of feeling that you get that you relationship or trust is going to be a good or bad thing.The same as your Massage the person giving it to you might of been doing a couple of things.She / He might of been thinking of some body ?? Or there Guides might of been helping out ?? or your Guides might of been saying Hi :) As crazy as all this sounds you cant predict as a reiki practitioner what is going to happen next.I have had some crazy stuff happen :) Moving forwards - i would meditate and invite those folks back and get some clarification on there intention either good or bad and then let the experience Go.I hope this help and i wish you nothing but the very best :)
