Cover art for Sunshine lyrics by Alice in Chains

The protagonist is sickened and ashamed, probably of himself, or maybe not only himself and finds relief in what he refers to as "sunshine". My guess is also that this one's about a mother raising a child on her own. It's important to note that (by my opinion) the verses are the child's words and in the chorus are the mother's.

Anyway,this song is No.1 AIC in my list and I usually don't have favorite songs, but this one means so much to me, I love it!

Very good!

Perhaps as well you might think of the protagonist as having lost a father (or male figure) for reasons beyond one's control.. longing for a connection that clearly isn't reciprocated. Doesn't really have to be the father, but since the mother was and is addressed forthright, it kind of made more sense it'd be a 'male' role model...

'Then some dude came down to touch the Mother, Mother touched, and dude ain't here no more... Suck your woman down'

'to brand some name across my back... so you care? Find someone to tell you!'

lastly- perhaps he...

Agreed with your interpretation, and the general consensus. Jerry Cantrell wrote this song after the passing of his mother, so it's an emotional one (with a cool riff).

The lyric "Then some dude came down to touch the mother" does seem reminiscent of the Bible (the birth of Jesus to the virgin Mary) - perhaps a way of portraying the Mother as a sort of saintly woman, while defacing the father as "some dude."

I agree he seems to be comparing himself to his father (who apparently runs off), and questioning himself as a person.

But...
