Given that everything we experience in this life is through our consciousness, equating depression to a shift in consciousness isn't heavy lifting. This is an association where I would like to see some hard science backing the link between our conscious experience and the underlying function of our wetware, the brain.
As far as subjective experience, I've witnessed myself slowly slip into a depression toward the end of a relationship I knew wasn't going to pan out. I couldn't put my finger on it at the time, but I slowly remembered sex becoming less enjoyable with my ex, the pull of my hobbies less exciting and rewarding, my global outlook on life and the vibrancy of my future becoming more dim and... depressing. This was anhedonia, the inability to feel pleasure. I felt like I was wading through a dark cloud. The ability to smile organically through enjoyable interactions and activities all but disappeared, or at the very least, felt forced and somewhat "empty", like I was a poor actor. I had to give a best man's speech around this time and was shocked to hear how monotone my voice had been while delivering the speech.
Throughout all of this, I more or less kept the same routines. I was spending more time alone but still managed to schedule time with friends, I kept working out, and never slipped into a dark hole.. but I'm not ashamed to say I wasn't able to solve it alone, in fact the shift was so subtle that by the time I had become aware of what conscious state had become, I was dismayed to find that I was already doing what most people recommend to get out of a depression - stay active, spend time with friends and family, spend time in nature, exercise, etc. Which leads me to what ended up working... therapy.
I can't say I've had any major trauma's in my life aside from losing my father as a teenager, but talking over my life with a therapist helped me come across some events that triggered me emotionally to revisit, and over several weeks I started to feel the cloud of anhedonia lifting and started to enjoy life as it appeared to me again. The major conclusion being the functioning of the subconscious mind on our conscious experience plays more of a role than I expected.
YMMV, but if you are experiencing depression, consider therapy.. this is coming from someone who was already experienced in the trendiest news grabbing headlines for treating depression before I realized I had become depressed, including meditation and psychedelics.
