A building to design, a play to stage, a coat questioned, a rib cracking

I helped in the internal construction of a building in several stages. In the first stage, it seemed like I was using an ultra-realistic 3D computer design tool. But basically, I was actually there in the building. First, I helped make sure a tall wall with repetitive structures on its face was uniform in color. I made sure the bottom floor was consistent as well. I noticed an irreparable flaw on one spot of the floor, and saw it was in the shape of a heart icon, so I laid in a design inside the shallow hole and left it like that. In the building, people were getting ready to stage a play about "Mary", apparently a figure from Greek or Asia Minor or Persian mythology/history. She had two children who were both half animal. Her son was half lion, and her daughter was half rabbit. When I actually saw the kids, they appeared to shapeshift slightly towards the animal form when they felt like it, but never seemed to be totally animal, but when they were in their human form, the only strange thing about them was their coloration (the lion son was pretty yellowish). Oh, apparently, the half rabbit daughter was going to be played by Angelina Jolie somehow. Maybe only the later adult version.

On the bottom floor of the building, next to where I had put in the heart design, was a chamber that seemed to also be a gas station. My car was parked there, along with some others. A big black guy was looking into my car, looking kind of concerned and confused. I unlocked my car, and he asked whether the wool coat inside was mine (because he also had one like that). I remarked that it was a pretty common type of coat. He asked if I had my name written on it anywhere, and I said I probably didn't, but when I checked the collar tag, it was written there.

Someone at the "gas station" asked me if I was part of the "____ Project" (I forget the first word), which was really just a little sign I had put up associated with the heart shape in the floor. I told him it was really just a one-off thing and nothing was really going on with it.

In the same dream, when I came home on a couple occasions, I lived next door to a weird, hobbly old guy, sort of a cryptkeeper type, named Mr. Treflenn. He always took a while to make it around the corner on his way to his house, and I usually ducked inside my place to avoid an awkward long interaction with him as he walked up towards his porch. Then I would come out and talk with him a little about the building project or other stuff.

The second time he came home and I was there, my mom noticed there was a single rib bone in his driveway, and just before he came around the corner, the bone started cracking violently. We ducked back inside. When he finally got to his driveway, I went to ask him about the bone. He was there with a younger, but still somewhat strange, woman, seemed like they were a couple. He told me the bone was a bad sign of some kind but didn't get too specific about it. I followed them onto the porch and towards the front door. On the porch I saw a cat I recognized, and gave her a pet and a few scratches. Reminded me of Ray's cat, Baxter.
