Giant Mutant Robot Dinosaur From Outer Space

This is not the first time I've dreamed about this thing. In my dream, I was hanging out with a couple friends, guy and girl. We were at this little house with sort of a play area inside and a large parking lot similar to a Wal-Mart outside. I remember I was standing outside, and I saw an airplane flying erratically. It kept doing loops and flying in my general direction before turning around. At first I wasn't worried about it as it was still very high up, but I started to worry and even ducked at one point as it got closer and closer with each circle. I wasn't sure what was going on or why. I looked towards the city in the distance to see what appeared to be a giant mutant robot dinosaur from outer space. It was huge, white in color, and had glowing green eyes (like big black gaping circles with glowing green around the edges) and a horn on its head that may have been glowing green too. It was tearing up the city like Godzilla and roaring what sounded like a loud metallic sound. I don't remember where my friends were at this point, but they must have came outside because I remember the girl looking at the dinosaur in the distance and saying that her brother, who went to college in the city, had to go to some help group or he would end up dead by this monstrous dinosaur. There were cars floating in the air around the dinosaur, and I remember thinking that I would go home that night while everyone else was watching this thing on TV and go to bed, hoping when I woke up the dinosaur would be gone. I also wondered why help wasn't coming this time, which is what leads me to think I've dreamed about this monster before. I was expecting some helicopters and military to show up and try to kill it or something, like before, but they didn't. As I remember happening before, the dinosaur was eventually calmed down and it opened up to reveal a human body with a metal helmet floating above an invisible head. I think I was watching this on TV as I was far from the city. The person took the helmet off to reveal what appeared to be a purse made of skin for a face, and stepped out of the craft. All the floating cars safely landed back where they had come from, and they packed the alien and her dinosaur robot into a white government van and drove away. I remember trying to be as far away from the van as possible, which resulted in me leaving my jacket at the indoor play area. My friends and I later went to a weird restaurant that served burgers and eggrolls, and I remember sneaking them an order of each on the house for the dinosaur alien person. They were mad at first until they saw who it was (this time a male) and gave up the food. I sang a song about the dinosaur alien from the news transcript, and it pretended to sleep, so I left, leaving the creature in the restaurant where it pretended to awaken and smile devilishly to itself. I remember searching for it underground and asking my friends who they had crushes on, but it wasn't really relevant to the dream. I also called the dinosaur Mr. Apatosaurus, but I don't think that was really the type of dinosaur it was (After a quick Google search, no It was definitely not an Apatosaurus.). It looked more Like a giant metal T-Rex fossil with glowing green eyes and a bent back horn. Like I said, I think I've dreamed about this thing before and just forgot until now.
