"About a week after she passed, I was walking with my phone and my phone took a photo. I didn't take it. I looked at it, and I saw this blue thing flying around [my dog's] head."
She then showed the orb in question and added that she also noticed the suspicious object in a snap she took of her stepmother, Nancy Chuda.
"It's breathtaking and amazing," the blonde beauty gushed. "It is my mother in spirit."
The model captioned the touching post, "Your loved ones never leave you 🕊️🕊️🕊️🕊️🕊️🕊️🕊️."
Many of her followers were in awe, with one commenting on the Instagram video, "😍I believe it 😇💗."
"Your mom certainly had a gift while here and I believe with all of my being that she connects from the beyond…" said another. "It’s always been about understanding the language that connects us, not whether it exists. She knew that."
