Cover art for Street Flash lyrics by Animal Collective

Street Flash is about the singer's experience of an emotional low and then a redemptive visionary walk through the city.

"Inside fever" is referring to inertia and self doubt brought on by depression, creative block, or just being bored and having cabin fever.

The singer describes that he has no energy to move, and can only see what he should be doing, but can't stop procrastinating.

This "fever" has given him a creative block. He says to himself that he should not waste the morning, but he can't get off of the couch.

Later (after the episode has passed) he apologizes to his partner for coming in late, and describes street scenes tinted with an expansive high, like the "up" phase of a bipolar cycle.

He became oblivious to time. The fruit in sidewalk stalls took on a psychedelic quality. He ascribes happiness to the couples he saw, and imagines their happy home lives.

He has forgotten his worries by taking this walk, but also suggests that he has experienced a manic episode and is referencing a stifled home and creative life.

The second part is a melancholy description of his domestic scene during one of these episodes. It is lyrically and emotionally jumbled, simulating his thoughts and emotions during one of these bouts with inside fever.
