Seventh child of a seventh child

Ok, so I've organised my file with all of this information in order.
I've kept the relevant families together - I know that they are all my family really but you know what I mean.
My mum's parents, dad's parents, their parents, etc.
It's easy to get a bit lost and very easy to get sidetracked.
For instance, my dad always used to tell stories about when he was a lad, also he'd say he was the seventh child of the seventh child of gypsies. Things like that fascinate me, and so I find myself looking for confirmation in the records on Ancestry websites.
Some things can't be confirmed on any website though. Like the dreams dad would have - he always said if he dreamed of his mother then something bad was going to happen - he said she came to him in his dreams to warn him of impending incidents, and he wouldn't be able to settle until that incident had happened.
Now, I'm not sure if dad's mother actually did come to him in his dreams, but I'm inclined to believe that she did, given what happened to me on the night that dad died.
I was on holiday in Germany. I lived away from home anyway and hadn't been home for a couple of weeks before going on holiday. When I had visited them, both mum and dad seemed perfectly well and I went on holiday with no reason to worry about either of them.
One night, after a busy day sightseeing, I found it almost impossible to settle to sleep. By the early hours of the morning I was worn out, but every time I started to nod off I could see my dad wearing striped pyjamas and lying in a hospital bed. He was agitated about something and I tossed and turned all that night. Every time...EVERY time I closed my eyes - there he was in hospital.
The next morning we were up and out early. We had a busy day planned and it was teatime before we arrived back at the flat. We were greeted by the news that my brother had been trying to get hold of me that morning - this was in the days well before mobile phones - and had left a message for me to ring him urgently asap.
When I got hold of him it was to be told that dad had suffered a massive heart attack the night before. He had passed away in the early hours of that morning.
I will always believe that Dad had come to Germany to tell me himself.
