This is a bit of and odd thing that i just want to know if anyone else has similar things happen… it usually happens in
ND’s but a character or more often an item is from a piece of media or reality. I mean one example is a very vivid dream i had when i was around 7. it was basically spider man swinging through some buildings. it only lasted a few seconds. About a year ago i had exactly the same thing and didn’t know if anyone else has had similar experiences
of course everyone has this. what do you think dreams are made of? 
your mind makes dreams from the images that stayed in your mind. most of the dreams deal with subjects that you care or cared or that are connected somehow with things from the past and things from now. dreams can be weird, but they often have something you have seen that affected you. you probably saw spiderman cause you used to like him when you were 7. i often have dreams with the characters i like. it’s perfectly normal.
seems like you don’t have dreams often to be able to tell. if you did, you’d know that a lot of them are like this.
well thats the thing… i do have dreams mad of similar things… still not sure why i had the dream again though 
… i just didn’t know if it was my mind having a lack of imagination
we never know why dreams are the way they are 
things are connected and reconnected with things from the past… you never know that’s why they’re interesting and fun.
good points… tbh iv always had troubles if over examining things, rather than just enjoying them
