Something walking upright

This dream is a very long one, but the first 3/4s of it is just the same basic thing happening. This whole dream my person is played by <PERSON>, for some odd reason that escapes me. The majority of the the beginning of this dream my character is traveling from her home to another home that I think is a place she plans on vacationing. Her ex husband came along as well and this journey to the vacation home is just a bunch of walking along abandoned roads and talking about random things. When the vacation home is finally reached everyone goes to their prospective rooms and winds down. Mainly I was just walking around the house listening to people talk, and it was when I was sitting on the bottom bunk next to my dream ex husband when I realized I was dreaming, because I am not, in fact, <PERSON> and I do not have an ex husband in real life. Upon realizing this I went lucid. I got up and started staring out the front wall of the house, which was made of glass. I was watching a bunch of creatures walking around and playing with each other in the front yard when I decided I wanted to create something. I was concentrating, trying to make a creature of my own to play with the other creatures, and I succeeded. Unfortunately the thing I made was more of a giant monster then a friendly creature. It was taller then the house, its hind legs were dog legs, it had long, skinny arms with clawed hands, its head was also canine with sharp fangs, and a skinny neck and body. It walked upright, but it was sort of hunched over, and it was fur-less, with pale white, purple spotted skin. I was watching it run around the yard when I somehow got it into my head that I needed to confront it. I went out into the back yard, telling myself that I was crazy, when the monster rounded the corner and started chasing me. I ran away from it to the far corner of the yard, which was fenced with a wooden fence, when I realized this thing would kill me, so I lucidly made myself impervious to damage. Just in time too, because it grabbed me and started lifting me to its mouth. I stuck my hands out and pressed them against its face, then lucidly gave myself the power to burn whatever I touched. Its face started to sizzle and it dropped me. I came to a sudden stop in mid air before hitting the ground, which was one of the perks of me being un-damageable, then got on my feet and started running from it again. I would also like to mention that my running was fa-nominal; I finally got past my mental barrier of not being fully able to do super human things in my lucid dreams without a mental strain and constant concentration. I ran like the wind when usually my running is very slow, like I am running under water. Anyway, It chased me around, grabbing me, then when it failed to eat me it would drop me. This happened for the rest of the dream until I finally woke up. All I want to say is, <PERSON>. Really brain, really??
