Scary stories? Conspiracy theories? Unexplainable events?

Here’s another (personal experience, about 10 years ago )

So unfortunately, my grandma was at deaths door. 🥺 She was at the hospital with all her kids, grandkids, great grandkids, etc. bedside. She was basically hugging everyone and telling everyone her goodbyes.
When I get near her, I’m sobbing of course. And she tells me “ Alexa” (yes like the Amazon product, no she didn’t like saying my full name ) you have to watch over your mother, never leave her like so many of my children have left me.” “Never forget about her, abandonment is the same as death”
I was shocked, I was like 12 at that time.
My mom stayed by her side, and when we got home, she called us and says that grandma has died. 🥺

Like 2 days later I’m in the backyard playing with some cousins. And I see like a grayish dress near the corner of the house (we had a lot of fruit trees )
I get closer to see what it was and it was her.. my grandma.. I saw her face and everything.. 😱 I was gonna say “Grandma?” But before I could speak she waves goodbye and vanishes

2 of my cousins see this aswell and we run inside and tell everyone
But to this day no one believes us ☹️
