I have some, all funnily enough involving my granddad.
MY grandad (mums dad) to whom I was extremely close died in 2004. DD1 was born in late 2007.
When DD1 was about 2 years 2mo her and I were laid on mine and DH's bed reading a book together before putting her to bed.
The landing light was on (as I fear the dark) and my bedroom door was slightly ajar, I had my back to the door and DD was facing it.
DD who up until this point had been totally engrossed in the book, looked up, past me at the door and said clear as day 'hiya gra gra T' I went all goosepimply lol, not least because it was the day before the anniversary of when my granddad died!!
DD has as far as I know never seen a picture of my granddad (I really must get some put up of him)
Another one;
A few weeks ago I had a hospital outpatients appointment, as I was leaving after my appointment (I had both of my DD's with me) we had to walk back through the waiting room to leave. A nurse followed us through to call the next patient, she called his name which was exactly the same as my granddad's name. DD1 said to me 'oh thats my gra gra T'
I went cold and admit I cried, I really miss my grandad.
At this point DD would have been about 2 years 5 months ish, I am not aware of her knowing my granddads name let alone recognizing it after some random person calls it out.
One more;
Not long after granddad had died (approx 6 months) I was at my nanas for the day and had gone to the toilet. Nana lives in a very, very small bungalow. As I came out of the toilet, into nana's bedroom faced the front room, through the kitchen, I could see someone sat in the chair my granddad always sat in. I could see the back of his head, just like my granddad, even down the fact he had a full head of hair with only sporadic grey in it. He even had his handed 'draped' over the arm of the chair.
In that moment I felt like I had been punched in the face, it was actually my nana's brother. I broke down there and then and cried
