Over the past few nights i've been watching spiderman3 and last night i finally dreamed that i was him and i was fighting the sandman. Then i kind of turned into a flying character and i flew just a few inches into space and a jet was shooting missiles at me. The other night i tried to summond a person in my dream by closing my eyes and visualizing that person but it didn't work instead a dog appeared. What i want to know is why didn't the person that i visualized appeare.
