Yes premonitions are a thing and I used to have them a lot.
The main one I remember was when I was about 12 and I had a dream that I was looking through a camera lens with night vision and I was watching a ship sink, it's bow was out the water. It had the date and time in the corner (around 2am) and was "recording".
I could hear people talking in a strange language around me, like Danish or similarly Scandinavian and they sounded panicked and distressed.
I "knew" that I was watching from a cliff top and it was cold.
I remember waking up (I don't know what time, but middle of the night) and then struggling to get back to sleep because I kept going back to the same "dream". People crying as we watched the ship sink.
I told my mum about it when I woke up because I felt so troubled by it. She hadn't been up long or watched the news.
I went into town later that day and on the bus my friend asked me if I'd heard about the ship that sank earlier today? I hadn't but I immediately knew what she was talking about.
When I got home I walked in and my mum stared at me, I said "a ship sank didn't it?" And she said yes and put the news on.
If I recall correctly, it was a ferry sinking in the Baltic Sea in early 90s, killed 800+ people.
I told my mum that I must be mad expecting her to scoff, she just told me that I've always been able to see things that were inexplicable at the time.
