Actually, I had a Portal dream years ago and it was cooler as well. It started off as me inside of the main female character, crying about my recapture and longing for suicide. Then suddenly, a portal appears in my cell and I see Malcolm of Unreal Tournament fame on the other end, and he's all "I'm busting you out of here!" Then we go around exploring and there's this one part where a little helpful droid says "Please take this 9 foot roll of tape(?) and lay it along this line" and Malcolm is all "Hell no, don't trust it!" but I do it anyways and then the tape inflates like a firehose and grows a little GladOS head orb and a snake mouth and starts screeching. All of the sudden there's toxic sludge flowing everywhere and we're both running like hell and just barely reach a bulkhead before it closes. Then we go up some elevator and at the top there's a floor full of Deus Ex cameras and turrets and Malcolm tells me to multitool them, but I tell him that my multitool skills suck. Then I wake up.
