Strange Dream about a field

Date: 10/16/2019

I had a dream about a field. It was very strange. It was a bright green, open field and it was beautiful; almost like the Windows Xp background. In a sense, it was almost a historic/sacred place (at least that’s the vibe I got from it). Some layout of how the field was setup: The middle center part of it dipped in quite deep into the earth, and the further you got from the center, the higher the field raised up. I remember walking around and exploring, but there was nothing except grass for miles. All of a sudden I noticed in the middle of the field there was a white flashing light from the ground (similar to a ripple of water) from the middle of the field outward and it would fade the further it got from the middle. It pulsated, continually every 5-10 seconds. Now, I notice, at the direct center of the field, there was some sort of vortex thing; blue-ish grey, with a mix of white in color. The best way I can describe it is: a cylindrical plasma matter going up for as far as the eye can see, being about 5-10ft in diameter. As I’m walking towards it, I observe it, I’m very confused. Then, a little girl came out of this vortex. I wasn’t scared of her in any way. However, I remember her saying she tried to get her brother back because he died in it. I go to touch the vortex and I wake up.
