What does it mean when you have two seperate dreams with a common theme?

I’ve had at least two dreams involving characters from the anime show called Dragon Ball Z and those two times, it featured Gohan in his teens (circa Cell era), blind, his eyes a flat bluish-green and glazed over with a film. The first dream, he had just been blinded and was training with his father, Goku, and friend, Krillin in how to use “chi” to sense things. Krillin tests him by chucking a pinecone at him, which Gohan catches without effort. This moves Goku so much that he walks out and gives Gohan a big hug.

The next dream involving blind Gohan takes place a bit later. Apparently, something happened in the timespan, as he’s now bitter and feeling helpless. He is in a desert traveling with a Bedouin-esque girl. He suddenly flies up into the air and says with determination: “I am Gohan…and I am strong…” before he begins to power up with a loud yell. The girl, shocked at the spectacle, asks him what’s going on. Moments later, a hovercraft appears. It’s Goku and co., and they were apparently looking for him. Goku sees what’s happening and is genuinely relieved that his son’s safe while amazed at how powerful the boy had gotten. It was clear to me that Gohan, at some point, ran away and had been missing for a month at least.

I've had those two dreams within a month. I wonder if that's my brain's way of trying to tell me something?

Have you all ever had two seperate dreams that had a common theme to it?
