Bruh, you actually helped me wake up today.
I was dreaming, and I slowly realized that some things don't make sense. I came to conclusion that it is most likely a dream, but I should still proceed with caution in case it isn't. Later I woke up. Yep, it was a dream.
I pet my dog, went on to check my phone and found this post still opened from yesterday. "That's funny. There's an oak tree just like that, right outside the window. I've been eating walnuts from it since I was a kid."
But wait a minute. Walnuts don't come from oak tree. Am I still asleep? This must've been walnut tree.

I woke up. This time for real, although I still questioned it for a few minutes.
