Dream of building

So, I'm new to this, but I just have to figure out what this dream meant. It started off where I was outside and it was really dark. I was looking into the sky and could see the moon really well, like it was unrealistically close to the earth. Then all of a sudden I could see a rocket launch from the moon (instead of leaving from the earth) and landed somewhere on earth. Then I was all of a sudden in a building, watching these astronauts prepare to leve earth. It was strange though because they were all in a long line standing on something that was electrocuting them (but it was making them healthier). I was standing by the line watching them and I started talking to this man. He seemed really intrigued by me for some reason, and he had to move farther up the line so I said goodbye.. like I was never going to see him again. I felt very sad and disappointed. Later he ended up coming back to me and we both seemed real happy.
