I've studied the meaning of dreams for a longgg time. the maniac killing animals dream is not that unusual-it is usually brought on by tension-if you're in a new situation or environment-Your animals mean a lot to you and the thought of losing them leaves you lost and afraid-abandoned-you're away from home so you are a bit uncomfortable. Before you go to sleep laugh a lot, read a silly comic, wear dumb pajamas, do something absolutely stupid -tension will go away!! Sweet dreams!!
