Shaggy Dog And Street Lights Are Confusing

In the past I have been very skeptical about what is out there as I like to rationalize things. I have stories that have happened over the years, which has forced me to believe. People in my life attract other worldly attention, and I must accept this, I only hope to help. I, however, hold up a shield after attacks. When anything else happens to me, it tends to be calm, and brush it off.

What I have questions about is about an ex roommate and my best friend. Both of them attract attention.

While walking with two roommates one day on our way to our apartment, my one roommate kept commenting that a medium sized dog, black and white spotted, and shaggy was following us. It was unexpected to see that, and it was odd watching her eyes go around the hallway where it was. I admit, it cheered me up, being very attached to my dogs at home and missing them terribly. My other roommate, who didn't see it, just blew it off, saying it's just a dog! Other times, she would see it walk around the apartment, many times going into my room as I slept.

After experiencing roommate problems, being depressed, feeling betrayed, I had to leave that apartment building, but I am still friends with the two fore-mentioned roomies. I moved in to an old house by myself, very creepy, but comforting to me, I just have bat problems.

I had my best friend come over one night. He saw a dog fitting the description walking around town with us! I never told him about it before. I was excited because he isn't even friends with my roomie, and he wouldn't know. Twice after that, he saw the dog in the alley by my house. Now he sees it at his house in Indiana.

I have been friends with him for years, and lots of things have happened around us. One thing I find confusing, and I can't explain. When we drive or walk around at night, every time we walk by a light, or streetlight, it will go off. Not every time, it just happens so often. It would be bright then, just go out. Other people comment on it, too. I have put it off for so long as it just happens SO often.

For some reason I would like to add that I believe him to be an emotional vampire. He stays up for days at a time. Every time we hang out, the energy is drained from me. I'm talking about being awake a few hours, after being well rested, seeing him, then feeling very tired. My friend just goes and goes and goes.

I am confused that the dog is around people I know, and I haven't seen it. Also wonder why it appears to my friend, who prefers cats, and shuns dogs. As for now, these are the only things I'm starting to question.
