Nice job man, this is the kinda weird I like, that somewhat vocal-sounding sample that plays the main tune in the beginning and end goes well with the mallet(ish) synths and I'd honestly would've described it as being otherworldly even without the "alternate dimension" prompt. That change about half-way including the pads worked really well, but I think you could've added more layers, I was waiting for a echoey bell to soar over the arps or something. I'll admit that towards the end there's a bit much repetition for my taste, the last section could be half the length and I'd like it, also the heavy reverb in the section between the beat and intro is a bit obnoxious, maybe tone it down and lower it an octave to make it less noisy. Other than that I do appreciate you finishing as you started, helps add to the surreal factor.
