Yes, it sounds improvisational and a little messy but if that's what you wanted to do, then there is no problem. I personally liked it, it reminded me a little of Scriabin, the very ending was the only part that bothered me, precisely because it was expected. I often have the feeling that young people use the word "dream" in a title as an excuse to lack form, sometimes it gets too surrealist, here it's ok.
