Yup. I had something similar to number 1.
Seriously.
That's when I first discovered that I have a mild form of (cryptogenic focal) epilepsy. It's now controlled by medication and I have had nothing since.
Number 2 has never happened. I might assume it was a dream.
As for Number 3 - well, we dream about all sorts of things, people, situations. Dreams are the manifestations of the subconscious mind - you won't find too many scientists arguing about that. I think such things need to be set against the number of times you dream and don't act on things.
It's like coincidences. Oooh, what are the chances of meeting someone you know from home on holiday? Well, pretty high, actually. Given the number of people you know, it would be more extraordinary if this never happened.
The night before George Harrison died, I had a dream about George Harrison dying. But so what? He's a famous guy. He's often in the news. I may have been listening to the Beatles the week before. With 6 billion people on the planet and only 365 days in the year, it would be staggeringly UNLIKELY that, on any given day, nobody in the world had a dream about George Harrison. And equally unlikely that nobody would have a dream about a famous person dying. I've also had dreams about Scarlett Johannson dying, but last time I looked she was in the best of health. I don't intend to email her people and worry her about it.
As for the rest - who knows? My point is not that it is impossible to ascribe supernatural explanations to things if you wish to do so. You always can. My point is that the overwhelming balance of evidence is that such things do not exist. Given a choice between a supernatural explanation and a scientifically-plausible one, I will always go for the latter.
