Vanishing suddenly

Color legend: Non-dream Dream Lucid Lucid #245: The Third Arm I am sitting next to Wife at a little craft table, both of us working on our laptops. I do not know what she is doing, but I seem to be writing some code for the game. My iPod is laying on the desk next to me, and I try to cue up some music on it. I swipe and poke randomly at the screen, and a song starts playing. Horrifyingly, the performer in the song is me! I am braying out some horrible-sounding song that is a cross between "Tribute" and just random squawking. I desperately stab at the screen to try to make this stop. Now some British synth-pop is playing instead, much better. I note how strange the screen appears, and I remember to look for the dream. I stand up, and find that both Wife and the craft table appear to have vanished. I remember my intention to summon <PERSON> and attempt the bonus Task of the Month (to find and play a musical instrument that does not exist in waking life.) For some reason, I have this very strong belief that the dream is taking place in my childhood home and that it is completely empty. I affirm that <PERSON> is already here in the room with me but I do not believe it. I walk from room to room, saying things like, "[<PERSON>], you are right around the corner..." but never quite believing it. I look down at my hands and say, "[<PERSON>], you are walking right beside me." As I say this, a third arm extends right out of my chest, lining up its palm with my own palms. The upper part of the arm is covered by the sleeve of a purple polo shirt. I wonder whether this is <PERSON>'s arm...? The purple sleeve seems really promising, but the arm kind of has a man-hand that looks more like mine. I think about what I can do with this to complete the summon, but cannot quite figure anything out before the arm vanishes. I proceed into the den, saying out loud again that I am expecting to find "[<PERSON>]" here (using her waking life name.) I say something about her being "purple", and expect to see her. As I turn my gaze around the room, I spy a purple director's chair in the corner, but no <PERSON> sitting in it. Again I expect to see "purple" <PERSON>, but instead I summon a purple trampoline, leaned up against the wall! And now look, there is a purple wall hanging over one of the windows. I peer through the window, seeing only darkness beyond. I feel like there is no certain dreamworld beyond this house right now, and even though I consider the idea of leaving, I feel nervous about trying this. Maybe I just need to try calling her "<PERSON>" instead of using her waking life name. I try this for a while, too, but I am having a terrible time shaking this idea that the house is empty. I sense that I have let myself get stuck and that I should be able to think my way out of this. I call out a few more times, noting that I have actually had quite a bit of dream time. I worry that I should have done more with the third arm or that cool-looking purple trampoline. It is not long before the dream ends.
