The other night I had a crazy dream. I'm wondering if /x/ can help me decide if A. It was just a very vivid dream, or if B. I somehow visited a Parallel Universe in my sleep. I'll >greentextit to make it easier to read.

>Place was just like Earth. Clouds, Bluish sky with a Red hue.
>Definitely a different solar system. I remember seeing two large celestial bodies in the sky. Seemed to be at Moon distance. One sun.
>It felt like I was visiting old friends. Everyone acted like they hadn't seen me in a very long time. I was extremely happy to be there. Didn't stop laughing and smiling and joking with everyone.
>Same friends I had here, for the most part. Some friends were people I don't know, or never met here.
>My old co-worker, whom I worked with for 5 years, was not my co-worker in this place. He was a child-hood friend. My best friend.
>I remember it being at a university in this futuristic city. You entered the city the same you'd enter a train station or airport. There were no cars. I remember taking a bus from somewhere to this city/university. Bus was filled with people who had came from the same place I did. Only thing else was a rail service that went in and around the city.
>Everyone was like they are here. Same clothes, fashion. Everyone was human.
>My whole dream once I reached the city was literally just catching up with old friends, asking them how they were, what they had been up to, what their plans were. This went on for what felt like a couple hours.
>I remember telling them, "I gotta go guys." and being upset I had to leave. Next thing I know. I wake up in my bed.

What do you think /x/? I'd love to hear some opinions. I wouldn't share if this wasn't something out of the ordinary for me dream wise.
