dreamers. please help!

i have read that spinning within a dream may help stablize and make dreams more lucid. may even change scenery! so far ive done this "spinning" in four dreams upon becoming lucid, everytime i get this feeling in my gut, and scared outta my pants. why is this????

the last occurance was last night after listening to some binaural beats and i actually fell asleep saying to myself, "I will not be scared. Its just a dream" over and over. actually raising my voice and starting to scream as i spun faster and faster and still, i got so scared i woke up.

comments would be GREAT!
