Papa said it was a sign of money in the bank, to begin with. Shortly before he died, he said that it was communicating beyond the veil.
I always speak to whatever pet I happen to own, currently kitten. Always felt the weird kid on the block as sometimes just talking to myself, I'd hear replies. Yup, found out I'm clairaudient. I got the gift from Papa.
If I'm crazy, so be it! If I'm paranormal well that's fine too. Either way for over 60 years now and many times it's been extremely helpful in staying away from potential residences which were haunted, phew!
One recent example, after my son died in 2017, I yelled to the ceiling and I began sobbing uncontrollably. Suddenly, I felt warmth surrounding me, and I saw my cardigan tightening around me and I felt a heartfelt hug followed by a whisper in my ear: "Mum don't worry, I'm no longer in pain. Please, don't cry..."
Usually these days, it's hugs from hubby in the kitchen, always with a whisper of what he called me giving me a hug when he was alive.
So, no insanity, it's a natural way to get answers from departed loved ones. Take it whichever way you want. Everyone will agree or disagree but that's my sincere experience.
