Wow those were some wild hallucinations from a couple of E's. But if I was that mashed the last thing I'd be doing would be driving around. It seems like any arguments about the safety of driving on MDMA can't possibly apply when you are hallucinating cars parked in the middle of the road
But anyway, I don't believe you had an MDA pill like some people have said.
There has only been one batch of Red Arrows in pillreports/ecstasydata databases, and it's the same one I've tried. It's a pill that has a good dose of MDMA and a bit of speed. A single Red Arrow is enough for someone with no or low tolerance to have a relatively strong, long lasting experience. I actually thought they were some of the best pressed pills I've had.
So you had two of these which is a pretty large dose of MDMA, plus a fair amount of speed. If you are sensitive to the psychedelic/visual effects of MDMA I'm not surprised you had such convincing and strange hallucinations, especially if their nature was driven by a degree of paranoia on your part. Personally I do get visuals from MDMA. A medium dose will give me only mild visuals throughout the experience, but if I smoke pot on the comedown I experience weird, random, clearly "phenethylamine" CEVs and some OEVs in the corner of my eye. As the dose increases, colors and patterns appear and persist long past the peak, and I've experienced some strange and convincing hallucinations somewhat like you described.
I also think that the kind of visual hallucinations that some people can experience on a pure MDMA comedown are probably more easily influenced by someone's thought process, especially if you are really scattered and getting paranoid and you're trying to get home on top of that. More so, I think, than the kind of visuals produced by more "typical" psychedelics. Some of the MDMA visuals I've had remind me of Datura trip reports because they can be so convicing and unexpected.
If you ever take a good dose of MDA you'll probably trip your socks off.
