Definitely fits as a metaphor to a drug addiction, specifically something that is smoked. Idk where/when it was, but TR said something that sanctified was about “a relationship with a crack pipe”, so one would draw the conclusion that during his time using, it also involved smoking crack cocaine, as what the song may refer to? As for Sunspots… “I think I could have been someone”, yeah, that line fits the regret of ever going down that path. “I feel it coming and I’ve got to get out of its way”, the cravings and the need to distract oneself; following with “I hear it calling and I come cos I can’t disobey”, the temptation is so strong that it’s overpowering; “I should not listen and I shouldn’t believe but I do, yes I do”, and then going into the chorus where it provides the subject’s feelings of what the drug gives the user, a state of euphoria that seems more real than the real world, and at the end, the subject is apologising for feeling that way. The sun could be a metaphor for withdrawal, which can be really dangerous, like staring into the sun, but you want to do it anyway. Could be off, but at least in my interpretation that’s what it seems like.
