OK, here's my interpretation: it sounds like the idea is that there is a scene going on for 4 minutes or so and occasionally we get some static, and that is when the ghost is passing through? If that's the idea, then the idea itself is good, but this felt to me like about 2 minutes of music stretched out to 4 minutes of time. If a song is going to go 4 minutes, I think it either needs to "go somewhere" eventually, or at least, lead us to believe it's going somewhere. This song coasts along very casually for the entire duration ... the sound itself is good, but I didn't feel like there was any reason for it to be 4 minutes long. Looking at your comments, I can see that you've layered together more elements than you have previously, and that's good, it probably is a more interesting sound than you had previously ... but there's still a difference between creating an good sound (which you did!) and creating a song that makes us feel like we are going somewhere emotionally or telling a story (which I don't think you did). That's not bad, but it's not complete, either. :) I think you should consider revising it so that every time the ghost passes through, the intensity of the music picks up ... as if we are getting increasingly nervous about the ghost we notice passing through. That would tell a more compelling story.
Of course, if my interpretation wasn't your intention ... please tell me what the intention was. I like the general sound, but like CeeeX, I'm left unsatisfied and with questions when the song ended.
