Just a thought: the cup of water is from Rei's room; could it be intended to demonstrate that the sequence is part of Rei's consciousness? Light and deep water, or something like that...
And what would the other images imply then? I don't think it's more than just another image from the show.
Oh, just for those interested, some of my finds from episode 22.
The creepy Baby dolls, probably meant to illustrate Asuka's fear of Dolls/ motherhood:
(Warning, those are EXTREMELY creepy):
To tie in with the "fear of motherhood", here's... An emryo with a huge eye?
The old man's silhouette and below, for sake of comparision, our only comfirmed glimpse of Mr. Langley (His hairstyle reminds me of Fuyu):
Something that looks like the windows of an expensive mansion seen from the perspective of a small child. Are those the windows of the house of Asuka's parents?
A... Triangle? Could also be a naked, female leg. Did little Asuka walk on on her father... getting at it with his new wife/was that trauma involved with the rejection of the plushie? They had sex within earshot of her, so I wouldn't put it past them to forget locking the door:
I have no idea what that is. Just a random psychedelic image, or do I see unit 02 in there?
This is also from EoE:
German text à la ep 22.
This says "Die!" but it's aparent that they used Google translate or something. It's the "polite form" of it, more like "Would you please like to die, Miss?" I think "stirb!" (simple, old, "Die!") might've been more accurate.
The second word here is "kill". Not sure about the first one, Asuka's eye is in the way. Could be "dich" (=a form of "you")
This says "Don't kill".
