Ok...first off, I'm gonna be really critical cuz you asked for advice, and this will help you.
I don't know why everyone starting out thinks they need to brand their videos by putting intros on their work...it's better placed at the end of the video, put us in the action first. I think that would have been more effective for what you're trying to go for. I think in the beginning, you focused too much on you waking up...it was a really long pause. I believe if you made it shorter, it'd be easier to the viewer to follow. I understand you were trying to build suspense, but it still dragged, you know? Taking more than 30 seconds to "wake up" is too long.
Also, compared to your intro music, your volume was really low. And when you woke up in the first dream, the camera angle was askew...half your head was cut off, which you never want. Gotta try and have the whole head in the frame, and again, too long to wake up. I could see that scene being like 10 seconds shorter and keep the same tone.
I think the "wtf" coming from Mr. Lion is partially because you took a little long to get to the point...but on a more serious tone, what is the point? I understand the gorilla is chasing you, but you have no real context as to why the gorilla is chasing you. We don't know if you did anything. We don't know if you know the gorilla. It doesn't seem natural...if that makes any sense. Kind of forced, you know? Like, your story doesn't have to tie neatly into a bow, but it does need context so we understand what's going on at least a little bit.
But that's just my two cents. Take with it what you will.
