Help: Weird dream about a guy I barely know...

I had a dream (actually a dream that recurred about 3 times), and in that dream, a guy (that I've seen only twice) is holding my hand but he swiftly lets go and leaving once we get to a certain spot then disappears until the next time we have class. **In real life, I have no romantic feelings towards him whatsoever, I have barely said a word to him**

Here's the in-depth section of the dream:

I walk down the hallway from a class in order to get to my English class. As I am going to English, this guy named Dave (who I've only seen/met a few times) grabs my hand and walks about 3 minutes with me until we get to the end of a hallway that is an intersection of 3 different hallways.
As I make a left turn he lets go of my hand and when I look up to ask why, he is gone :shock: When I go looking for him, I think that every other guy is him but I can never find him. But he always ends up coming back the next day to walk with me again :)

What does this mean?
