Interesting thread. I figured I have to chime in since recently I went through a discovery phase where I did paranormal investigations for a few
years. I'll tell ya what, I learned a LOT about the field even though I am a good skeptic. Still undecided about "ghosts" but I do know for
certain that there is clearly more to our universe than "meets the eye" (or other empirical senses).
Anyway, when did you move into this apartment? Do you know who lived there before you? How long has the 40 yr old lived in the complex?
When you moved in, did you do any "cleaning" of the place? By cleaning, I mean spiritual cleaning by burning sage. That is known to clean negative
energy away from a dwelling. Maybe it is BS made up by the sage growers union

, maybe not.
If you moved in recently, did you have the locks changed?
Also, make sure you have extra batteries for that camera. It is amazing how Murphy's Law can kick in when things like this happen. You will have
100% charge and then as soon as you are ready to get a shot of whatever it is, dead batteries. It happens all the time.
The time-shift roommate thing is interesting too. Was this the same roommate that saw your double in your gf's window? Have you re-created the
incident where you go into her room and sit at the computer while they go outside and look up? They may notice something different between what they
saw before, and the real you.
Do you know how the cats were killed? Normal animal battle wounds or mutilation?
Lastly, a gun does nothing in this situation. I know, this is ATS where the first reaction for everything from a homeless cat-eater to a bee sting is
to get a gun, but you don't have to. It sounds like where you are at is rather well populated and this thing is not threatening you directly.
In my few years of paranormal investigation I find that emotion has a lot to do with experience. Is anybody going through additional stress? Of
course, this is something occurring out in the pkg lot of your apt complex so it does not have to be you or your roommates...
Somebody else mentioned to write down a log of the incidents, and another person advised to do EMF / EVP work. Those are two great ideas. If you
decide to keep a log, write down the following:
date, time, temperature, humidity, incident details.
You can get a cheap EMF detector from ebay - you don't need to dump a ton of cash on a tri-field or anything. Go walk around the parking lot with
the EMF detector and see if there are any unusual pockets of EMF (the malfunctioning light pole might be a source). Then do it again the next day to
see if your readings are consistent. Now you have a baseline. If you see this thing in the parking lot again, go down as soon as it is gone and
check for unusual EMF that varies from your baseline readings.
EVP may or may not work for you. There may be so many people around that you will pick up voices / sounds from other residents at all hours thus
making it near impossible to catch any good EVPs without contamination. I had a case where the house seemed silent (could not hear anything with the
naked ear) but lo-and-behold I had what I though was excellent EVPs all over the tape. Turns out I was picking up voices of people at the bar across
the street. The recorders will pick up more than your ears can and in a well populated area of night-owls (like a university) you will get this type
of contamination all night long.
I'd be willing to answer any questions.
Oh yeah, somebody else mentioned a medium/psychic. Be careful if you decide to do this though - test them first. I never believed in mediums /
psychics before but in my paranormal investigation days I did manage to run into two excellent psychics. Blew my mind, actually. But in finding
those two legit people, I ran into dozens of crackpots, scammers and psychos.
