What are athlete dreams about?

Hi there! So tonight i was dreaming myself running extremely fast (like an athlete) with some kind of small dog with dark brown or even black fur. What this can mean? Asking this because the dream was vivid, i can clearly remember it, maybe it means something.

I had a dream where I had come back to a type of acrobatic/climbing school after disappearing from it for two years (no idea why). It was like one of those specialty schools where even the design of the school is made to facilitate the sport. I had been the number one in the whole school but I disappeared mysteriously. Oddly only a few actually knew what I looked like. I walked around visiting my favorite places that I remembered. A close friend recognized me and we talked for a while about the old times as I continued to visit around. The place was full of climbing areas and swinging ropes and stuff everywhere. Athletes were called "runners" and there were a bunch of courses of various difficulties called "runs". Each run had a difficulty level between 1 and 10. There was a run of difficulty 8.5 that lead to a special "bar" for exceptional athletes only. You would receive a special tattoo that proved you were someone who had made it and it gave you special privileges at many places around the world. I went up it with little effort and went to the bar where the bar guy recognized me. We were chatting for a bit and one of the more exceptional runners who was always a douche, Mickey, saw me and made a big deal out of it. Then said he was above me now because he was one of only three who had completed the new 10 point run that had been put up. I ignored him and went to leave the bar. The barkeep told me not to try the new run after being gone for 2 years. I said ok, but went there anyway. No one had been able to do the run after their first try, even the current number 1 runner named Suzanne. They scanned my tattoo in as only tattooed runners could try it. I quickly watched a successful run done by the number 2 runner, Skyler. I then went ahead and I flew around, climbed, swung on ropes, and jumped. I made it to the end barely catching the edge of the end zone. I was the first person to do it on their first try and people began gathering as they recognized my name. I hadn't come down as my muscles were maxed out from the run. I decided to climb to the top of the run area and use the ropes around campus to escape again as I didn't want to talk to the people trying to interview me. I woke up about there.

In the dream my fiance (who is model handsome IRL) was some kind of athlete and was famous. Like a swimmer or something. He worked closely with a woman who was his coworker. She's physically perfect. He eventually finds out that she's pregnant and the baby is his. I break down sobbing and ask how long he's been cheating on me. He very nonchalantly tells me that they have sex all the time and it's no big deal. In the dream I'm completely broken and end up getting pregnant by him myself to prove to myself that he still loves me and that I'm a real woman. But no one cares that I'm pregnant because he and his coworker are beautiful and famous and everyone thinks they're perfect together.

I feel so gross and slimy. I know it's just a dream but he has emotionally cheated on me in the past and that wound never healed. I also brought up the idea of adopting instead of me getting pregnant (we're planning on having kids in the next few years) because pregnancy is terrifying and he literally ignored me completely and just started talking about something else.

26 July, 2018

I dreamt that I logged into Facebook and somehow accidentally was on the account of someone else. Instead of my own like I was trying to log into, it was a random athlete (I think it was a tennis player) from Europe. I remembered that this wasn’t the first time I had accidentally logged into his account.

I opened Facebook Messenger and saw a message from a random fan girl. I replied back with a random emoji. After that she sent another message that I don’t remember.

I found it funny that she actually thought she was talking to a famous athlete, but I also felt kind of bad that I was deceiving her.

It isn't my first time meeting other worldly entities but this one was different. It's the first time I met a demon.
In the dream I was playing in the backyard of a house out in the fields. In the distance there was a pine forest, not very big but the trees were incredibly tall. From the forest came a man, a hunter. He was dressed with a black t-shirt and dark camouflage pants. He was looking for prey when he saw me and got close to the fence that limited the backyard of the house from the golden infinite fields and the forest. When he got there, he just stared at me as I was playing. I noticed him and got close to see who he was, I had a sensation of fear.
The demon had killed one of my chickens. I asked him why did he do that and he just said "I was bored" while smiling. His face was unsettling: very pale skin, black hair pulled backwards but still messy and ice blue eyes. He was a young man, slim but muscular, the physique of an athlete.
We kept on going with the conversation but I can't remember it all. I just remembered me asking him if he was going to kill me to which he replied "no" and telling his to not swear and he replied "well, I'll stop if you want me to". He was always smiling and he had a look of arrogance in his eyes, as if I wasn't worthy of talking to him.
At the end of the dream my mum came out to pick me up and tell me I had played enough, but she didn't seem so see him. As I went away with her, he stared at me and telepathically told me: "Barbatos". Which I guess was his name.
