Right on, it doesn't mean anything, its looking for omens. The demons can and will actually work against you through these 'signs'. When I was doing drugs like marijuana and lsd a few years back, these 'signs' became so influential over my life that I came to think that aliens were coming after me and I even tried to kill myself because I was afraid they would capture and torture me (no lie, this was before I was found by God). I was in my right mind (I am not schizophrenic) but I was believing the demons and their murderous plan to end my life. I am telling you the truth, the demons were after me with these 'signs' left and right and wanted me dead. I had fell into believing something which was not true and it changed my life forever. I ended up in the mental hospital. But later, I found out also that I was being demonized, and that this was why it was happening. I became possessed in my body by demons,,, a legion of demons.
