I'm NOT saying this was the intention (I'm just simply putting it out there) but the
"line that he messed up" according to some people could be percieved as just being a natural and realistic piece of dialogue, in Stan's situation at the time. (3rd verse)
Like this text in the quote box below says; Stan was about to commit suicide by driving off of a bridge, after drinking vodka. He was obviously drunk, and his words were slurred and he was clearly under the influence of depressants, as evidenced in the line "I'm on a thousand downers now, I'm drowsy"
Stan also mistakenly referred to Phil Collin's "In The Air Tonight" as...... "In The Air Of The Night"
^ That was clearly deliberate
And the whole sleep/dreaming thing, maybe Eminem thought it "sounded good" and was good/realistic anger that Stan would actually say, and he could get away with it due to Stan's current situation??
The third verse is Stan recording himself onto a audio cassette in the car as he is about to commit suicide by driving off of a bridge after drinking vodka. His words are slurred, and he is clearly under the influence of depressants, as evidenced by the line, "I'm on a thousand downers now, I'm drowsy." His pregnant girlfriend can be heard screaming in the trunk (he even stops himself for a moment to yell at her: "Shut up, bitch, I'm tryin' to talk!") and the rain and thunder are loud and insistent. Stan, enraged, addresses Eminem as "Mr. I'm-Too-Good-to-Call-or-Write-My-Fans". He explains his predicament: "I'm in the car right now, I'm doing 90 on the freeway/Hey Slim, I drank a fifth of vodka, you dare me to drive?" (quoting "My Name Is" on the previous Eminem album, The Slim Shady LP). This is followed by a reference to a Phil Collins song "In the Air Tonight", misquoting it as "In the Air of the Night." Specifically, Stan refers to an urban legend that the song is about Collins seeing a man drowning, while a closer bystander does nothing to save him. Screaming is heard and Stan reveals that his pregnant girlfriend is in the trunk suffocating "Shut up bitch. I'm tryin' to talk, Hey Slim, That's my girlfriend screaming in the trunk/But I didn't slit her throat I just tied her up," once again referencing Eminem's song "'97 Bonnie and Clyde" in which Eminem implies that he had slit his wife's throat before putting her in the trunk and dropping her off in a lake ("And don't worry about that little booboo on her throat/It's just a little scratch, it don't hurt/Her was eatin' dinner while you were sleepin' and spilled ketchup on her /Mama's messy, ain't she/We'll let her wash off in the water"). Stan vents, revealing the depths of his anger: "I hope you can't sleep and you dream about it/and when you dream I hope you can't sleep and you scream about it/I hope your conscience eats at you and you can't breathe without me!" At the end, Stan realizes too late that he will be unable to send the tape to Eminem ("oh shit, I forgot, how am I supposed to send this shit out?"). A car crash then follows, as the car breaks through the bridge's rails and falls into the water below
