My parents moved to Florida, I rarely saw them.
And as my Mum got older and I spoke with her on the phone occasionally, I noticed she wasn't the same. She also got quite nasty, which wasn't like her at all. So I knew something was wrong but my Dad wouldn't speak about it.
One morning I was in the kitchen taking laundry out of the washer to hang it. It was a beautiful day and I had the door open.
A huge gust of wind came flying into the door, and two small black feet were walking into the kitchen, the legs starting to form. I screamed and it disappeared.
I knew it was my Mum because of those small feet, she was a tiny person. She passed away from severe dementia / alzheimer's, not sure which, but it was the dreadfully violent type.
Two years ago, I woke at 4:00 a.m. gasping for breath, my throat had closed completely. Panic-stricken, I ran to the sink and managed to drink some water which opened my throat.
It was very puzzling, this had never happened to me before (or since). The first person I thought of was my Dad, and sure enough he passed away a few days later, at 4:00 a.m.
