According to my friends my dreams are freaking weird

Is it a common thing to be able to control your dreams? I seriously don't know if this is normal or not. In my dreams, I can control what I do (but can't control the surroundings), I have my own thoughts and use logic, and can remember things from real life. Let's say my mom told me to pick up a sock off the stairs. In the dream, I might see a sock on the stairs. A few days ago I was singing to myself in the dream, and I'm positive the lyrics were correct. And even if they weren't, I still knew what the song was.

I'm almost never truly aware that I'm dreaming; it just feels like an alternate reality. I have been able to wake myself up a few times. I basically just thought "ok I should wake up now" and then just did it. I chose to; it's not like it was fading away and I was suddenly aware I was awake. Another time, I was panicking about something I did, and I just realized suddenly, "Wait, I'm dreaming, it's ok!" and then just enjoyed it for a while longer before I woke up.

So does anyone else get this??
