I had a strange one a little while back when I was camping at Lake Powell: in my dream I was an F-22 Raptor. I wasn't piloting it, I literally was the plane. My perspective was over-the-airplane's-figurative-shoulder, like in Ace Combat: Assault Horizon's Dogfight Mode. (Which is probably where the dream came from, except I'd been camping for a week with my only electronics being my phone and my old Gameboy SP. If anything my dream should have been about Pokemon)
Anyways, there was this big epic air battle going on, with 'Through the Fire and the Flames' blaring in the background. We (myself and some allies that I never saw again after splitting off from the main group) were fighting what looked like Eurofighter Typhoons over a big metropolitan area with a large amount of cloud cover. I chased a bunch of the enemy planes down and blew them out of the sky with my machine guns. This sounds boring, but it was a moving experience. I didn't just watch all of this happen, I felt it too! I was the plane, I could feel the push of my afterburners, hear the roar of the Vulcan cannon, feel the stress on my airframe as my control surfaces shifted, and had feelings of giddiness (and in one case dread as an enemy came up behind me, but this quickly turned to elation and mad laughter as I executed a counter-move and got in on his tail) as I soared through the sky, unchallenged and unopposed.
The whole thing ended when I chased one particularly good opponent up above the clouds into the clear blue sky. For one shining moment, everything froze, their plane was sitting there, completely vertical in the air before me. I saw the sunlight glint off of the canopy, felt the glare of the sun to my upper-left, everything seemed so quiet and peaceful up here, above the noise... And that's when a ribbon of bullets from my cannon and two sidewinder missiles tore the plane into five or so different pieces and I roared through the wreckage, feeling bits of oil, gas, and shrapnel impacting my nose.
Then I woke up, and that dream has been on my mind since, it was so epicly awesome.
