Trains and Space Shuttles

My dream was interrupted by a call of nature - So I had to cut into it and then I really couldn't get back into it - sadly. It was a interesting one.

I was in a large building like a school or castle and was getting ready to board a train to go learn more. But the train was full of dead boys/their ghosts.  A man next to me sent in his familiar? Another ghost, to get the hoard of ghost boys off the train and they left in a mass and I could see them running along side the train - it was darkish, like early morning.

I remember most of them were gone so I jumped up on a platform in between cars and 2 of them stopped to stare at me. I said in a low flat voice that they had to GO NOW they weren't to be here and they ran off. Like I had some power to also make them go?

That's when I woke up - I need to try to re-enter this dream later.

And being a NASA junkie - 
Also of note today is a NASA launch! From their website:
A new era of human spaceflight is set to begin as American astronauts once again launch on an American rocket from American soil to the International Space Station as part of NASA’s Commercial Crew Program. NASA astronauts Robert Behnken and Douglas Hurley will fly on SpaceX’s Crew Dragon spacecraft, lifting off on a Falcon 9 rocket at 4:33 p.m. EDT May 27, from Launch Complex 39A in Florida, for an extended stay at the space station for the Demo-2 mission. The specific duration of the mission is to be determined.
As the final flight test for SpaceX, this mission will validate the company’s crew transportation system, including the launch pad, rocket, spacecraft, and operational capabilities. This also will be the first time NASA astronauts will test the spacecraft systems in orbit.
