Nightmares.
I remember, as a kid, all it took for me to be terrified was a good monster or parents-turning-into-spies-for-aliens-and-abandoning-me nightmare. I can’t remember the last time I had a surreal nightmare such as that. They have been replaced by realistic fears. I just awoke from a dream where an ex-girlfriend of mine turned out to be pregnant, and my life was turned upside down. In the dream, I remember just trying to be the strong guy and telling her no matter what happened on the past, I would be there for her. I tried to be responsible. But I remember just collapsing and just breaking down, something I never do (especially in front of others).
After watching my life unfold, I wake up on my couch to my mom shaking me and telling me to go to bed. I was in a cold sweat, but just so relieved that it was just a dream. It got me to think, though. I just realized how much I have changed, and how all aspects of my life evolved, accordingly.
I also realized how much I miss the monster nightmares.
