interpret the last part.. why? did i lose it? what does it mean?

[ostensible]

i didn't know about lucid dreaming until last night. i read a lot about it and i realised that this happend to me sometimes in my dreams. so last night i had a dream that i was walking down a dark, lamp lit street with my friend and i asked myself if it could be a dream, i didn't know so i tried to levitate for a second. i did. i almost woke up because of this but i tried spinning around and told myself to calm down.

then i imagined fall leaves, and they were there. i could now control where my dream went, to test things i sort of bounced around and flew while my friend walked. after awhile i lost control and it turned scary like a lot of my dreams do sometimes. [[ i was on my bed in my room.. this may have been why i couldnt tell the difference, and a big black dog had the sheets in its mouth, growling and trying to get to me.

then my friend pulls it out of the door after some struggle and said "i've been able to pull him away twice legally." it was weird. because i don't remember anyone ever talking in my dreams before, only thoughts. the dog scared me, so i woke myself up. i was happy cause i actually went to bed and decided i would try to do it that night.]]
