All about horror so I'm excited to really get into this. The opening of drowning in light is as dark as expected. Great choice of voicings here; offsetting the organ sound with piano to emphasize the chords is clever. Percussion adds some nice rhythm and pulse to the track, and I do like how the snare is heavily processed. Makes it stand out in a good way.
Daybreak Illusion has some really gorgeous pads at the beginning, loosely reminding me of some of the more ambient works in Resident Evil 7 in particular (think Floating In Between). There's some great use of the stereo-field here with plenty of elements panned to really take up space. The lack of percussion in this is a boon - keeps this track feeling airy and suspenseful without having a grounding rhythmical element to attach yourself to.
Blackened Air has some neat sound design off the bat. Great motion at play and the mixing does wonders for this to really sell the ambience. The very faint tones that we do hear are all well defined but never too "obvious". Of course the mid-way point hits and we are thrown into this distorted grinding that begins to fade out as the bass creeps back in. Genuinely some incredibly creepy feelings here.
Self Encounter (great title) is the busiest of the bunch. There's no ignoring that tribal percussion and the unrelenting metallic screeches and distorted squeals. I can't quite put my finger what this reminds me of - some kind of late PS1 or early PS2 title that opted to lean more into sound design than outright notation. This track is as oppressive as they come - one you breathe a sigh of relief over when it stops playing and you've escaped the threat.
Re-Forget has some more standard instrumentation, which is a welcome change after the previous tracks. Nice melodies and just the right amount of post-processing to really make the individual elements pop. This actually reminds me of something Akira Yamaoka would do in and around the Silent Hill 1 era. I think the guitar is just a little too MIDI sounding for my tastes, so I'd probably swap it out for live or add some humanization to get it to sit a little better in the mix. Hell, an clean or very slightly overdriven electric guitar would really lean into that Yamaoka vibe if that was what you were going for.
As a whole, this is some great work. I love horror so seeing people intentionally lean into that is always going to spur my interest. Production across the board was pretty good and the tracks are all distinct. Great job! Best of luck.
