This line is a reference to Hank Locklins' “Send Me the Pillow You Dream On (1958)." It is also likely that Morrissey was specifically influenced by Dean Martin’s 1965 cover.

This part has Morrissey essentially stating, “Listen, I know that we can’t be together due to our differing social status within society, but I still want to be close to you somehow & share my dreams with you. They may be the same dreams as yours.”

Morrissey is identifying himself with Joan of Arc in these lines, one of histories best known “bigmouths” for speaking her mind to royalty and being herself no matter the consequences (a sentiment that got her burned at the stake). There seems also to be the suggestion that inspired bigmouths will continue to appear and "strike again” throughout history only to suffer prosecution or be disregarded.

The line is also an indictment of Morrissey’s own big mouth, which metaphorically grew bigger with age. Morrissey is known for mouthing off about the Royal Family, politicians, musical artists, and too many other subjects to name. In later years, Beyonce, Madonna, and Justin Bieber have felt the the vocal stabs that Morrissey hands out with inherent ease.

The lines refer to continuous torture Syd experienced, being left in a dilemma:

In the dark obscurity, hidden from public view, 1) Syd was haunted by the past. Shadow, in that sense, communicates the idea of the past, as one’s shadow is behind someone. 2) Children tend to fear shadows in dark bedrooms, believing they are evil beings. It is a common occurrence that the child will perceive the shadow of furniture as a monster (pareidolia). It is even featured in a scene in the Wall (film). As Syd was thought to be a schizophrenic, the lines communicate the idea of being afraid of what is not actually there (hallucination).

In the light describes being under the spotlight on stage, performing for the audience. Being exposed colloquially refers to being nude in front of others, though in Syd’s case, that is revealing his condition. In his late performances with the band, Syd would play on the same one chord for the entire duration of the event or simply stand idly. The revelation was his condition, resulting in humiliation.

Thus the dilemma is that in the dark there is panic, and in the light there is humiliation, leaving him with no positive options. The screams in the guitar solo characterize his torture well.

His madness was frequently exposed in the lights of concerts, among other things. At some concerts, he would strum a single chord the entire time, or not play at all. At one he slowly detuned his guitar, and during one interview he simply didn’t respond to any questions. The lights of one concert melted the copious hair gel he had put into his hair for some reason, which then melted down his face.
