I see dead people, maybe

There have been many occasions where I have seen ghosts or just weird things. My latest, i woke up thinking there were wild flowers around my next one night, I tossed them off and went back to sleep. Then when I woke up in the morning, I caught myself trying to find the flowers I had tossed to pick them up. Of course there were no flowers there. The next night, about the exact same time, I woke up and saw this little old man walking towards me. He was wearing a bright orange shirt and blue pants. As he got closer, he faded away. Then the next night, my carbon monoxide detector went off 3 times, around the same time again. I unplugged it, plugged it back in and hit reset. It was fine. Its brand new too, so maybe there was just a power surge, who knows.
