Interesting.

In February 2021 I had a dream where I was outdoors, looking at the sky. It was late afternoon with the sun not a long way from setting, not very strong. Suddenly, a second sun appeared in the sky, much brighter than the first. It started increasing in size as if moving towards me, towards Earth, very quickly. In the dream I said to myself in awe "so it is true!", thinking that it was about the "Nibiru" event. The new sun quickly grew bigger and bigger, brighter and brighter, it filled the sky in a wall of intense white light. The earth and myself were about to be completely swallowed by it. Then I woke up.

Nibiru in the dream was not the point. It is not to be taken literally. It was just my mind conflating things, because some sources call it "the second sun" when it would appear in our skies. The important aspect of the dream is the SUN, the LIGHT, the engulfing of the earth and everyone in it by the NEW SUN, by the LIGHT. It is the same message as in your dream.

The old sun in late afternoon describes the end of a cycle. The new sun announces the beginning of a new cycle. The fact that it is much brighter and fills the sky with blinding light speaks for itself. The fact that it comes towards us to "devour" everything in its path speaks for itself. It is the burning off of the old. Same message as in your dream.

I doubt that a second sun in the sky would pass unnoticed by people all around the world.
