A concept of psychology that I will most likely remember in 5 years is sleep and dreaming. To me, sleep is a strange thing to think about. We are alive, but not fully conscious of what's going on. I find that dreaming is very interesting in the way that we perceive things that aren't actually there. There are days when I have very vivid and active dreams, and others where I can't recall any in the morning. I also find it interesting how we are paralyzed in our sleep so that we can dream without acting it out. Sleep and dreaming will always be a part of everyone's lives, and yet it's still so weird to think about.
I don't think I have ever sleepwalked, but I know someone who does and it just fascinates me. He has absolutely no idea what he does during the night. To me, finding out about what I do in my sleep would be a little scary because it would feel like it wasn't actually me. I have been told that I talk in my sleep, and I've been told that sometimes it sounds like a different, indistinguishable language, which freaks me out, because I only know English, Spanish, and French. Finding out strange sleep patterns will always interest me and I hope to learn about sleep and dreaming more in depth in the future.
