We played with an ouija board a few years before that event so I'm not sure if it's related.
But things progressed in the weeks before that event. We were hearing strange noises around and outside the house past midnight.
It sounded like there's a old washing machine flying around the house outside but we're not seeing anything. I thought at first it was funny because it sounded funny.
And then that night, things started vibrating. It was something similar to when a large aircraft flew very low above your house. Except there was no aircraft and it didn't stop until I woke up.
In the nightmare, I actually saw what was happening. There was this deep, rumbling noise that sounded like a large jet aircraft. There's a pale, slender man in the room who wore a black jumpsuit. He sat in my bed and gave me something which looked like a cylinder seal and there's engraving on it which I couldn't read. He told me I'll be using it in the future.
The man looked a bit and sounded a bit like me but is much older. And then I woke up, saw the man who flew out the window, the noise and shaking got worse for a brief moment, and everything stopped.
I never saw the cylinder seal in real life. Maybe it's figurative or symbolic, I'm not sure.
