Oh yeah, memory is a funny thing indeed.
I can absolutely remember the house I was born in, we left it when I was 18 months, there are just two memories though... one, crawling backwards down the step from kitchen into the lean-to garage attached, and the other is the cupboard doors, a bleurgh 70s or even 60s shade of dingy green - they were in the kitchen and then when my dad put in a new kitchen they were moved into the garage/workshop.
I've no reason not to think those are real, we have no colour photos of that house, my parents lived there only three years and only bought it as it was an end terrace next to my Grandma, Dads mum.
At almost 2 I remember going to visit her in a care home or hospice, there was a road roller on the way there and she wouldn't let me have a pink wafer out of the biscuits we brought her.
Why those events and objects are more important in my memory than say, the day my sister was born (18 months, literally a week after we moved and a home birth), moving house etc, I don't know!
My sister was a fairly traumatic child to live with and she would push our Mum around (and she was a fairly traumatic person to live with too!)...
Sister swears she remembers Mother falling or slipping off her bed and cracking her head on the bed frame and passing out, and then she apparently ran around yelling for help...
I remember seeing my sister KICK her off the bed, where she did knock herself out on the way down, and my sister calmly getting up and walking out of the room. They had been arguing, I think my sister would have been about 11 or 12 perhaps. I sorted it out, and then found my sister downstairs watching tv as if nothing had happened.
She swears her version of events is true, however at 17, during an argument with ME, she threw a dumbell at my head (4lb), and whilst I was passed out (only briefly) on the sofa bleeding, she ran off. When i came round and went to get help she snuck back in, tried to clean the blood off the white sofa (failed) and then... went to the pub with MY FRIENDS claiming she'd no idea where I'd gone, thought I'd gone to hang out with a different friend...
I had her arrested for that, to her shock, but she was held two days and then juvenile court and I was bullied into letting it drop by literally everyone.
She still claims she thought I was putting it on (I had a minor fracture of the skull and needed 6 staples in my head, I had bled sufficiently to ruin three sofa cushions and the blood was pouring out even after I had come round and gone to find help) and so she went out!
I have no idea if she really knows what happened and is still bullshitting at nearly 40 years old or if she blocked these things out.
