Sometimes I dream....

Sometimes I dream of flying, which I think is weird. I also dream of visiting people I miss like my family members who I dont see for years. I also dream about things I like. I heard that there was scientific proof that what you smell before you go to sleep reflects on whatyou dream. If you smell something good like perfum you dream of something positive. If you smell something bad like rotten eggs before you go to sleep your dreams end up negative. For some reason I want to try it out myself and see the results.
