I posted this comment on another thread, but I believe it is worthy of its own topic and possibly more in-depth discussion.
How our Grief, Sorrow, Sadness, Depression, Guilt & Regret May Scare Away Our Pets Spirit
In my own extensive research of the paranormal and spiritual experiences, and my personal / firsthand experiences, I have found that severe grief can scare away our lost loved ones from visiting us, as they can misinterpret what we are feeling. They can mistakenly believe that they are causing our grief, sadness, sorrow, guilt and regret and they don't want to hurt us. So their spirit can depart or stay away.
Think about it, our pets never, ever wanted us to be sad, depressed, angry or frustrated. They wanted us to be happy, joyous and content. They saw that as their job. Their responsibility. To cheer us up each time we saw them. To entertain us even. To make us laugh. So if they visit us in spirit, and we don't react positively and just continue to suffer, they may misinterpret that as their being the cause. They are not used to us not cheering up in their presence.
I noticed this occur when I picked up my cat Marmalade's ashes. I was expecting to feel absolutely nothing. I was calm, lucid and focused. But there was an energy around the ashes. I could feel something distinctly present around them. By the time I got back to where my cat and I resided, the energy was so, so strong, I felt that I was about to me lifted off of my feet. I held the ashes as I looked at photos and videos of Maramade, but I broke down and wept and wept, and as I did the energy faded. Until it completely dissipated and vanished.
To this day, over 15 weeks after his departure, when I remain calm, grateful, humbled and am at peace, I can feel my cat Marmalade's spirit much better and clearer. He is present. I can feel him all around me.
So I believe we should all be mindful of this possibility.
All my best regards,
