Heat Signatures on IR Thermometer Cameras

Here is a very valid question.  If ghosts supposedly create "cold spots" then why is it when they are supposedly caught on Infrared Thermal Cam's... they are registered as heat signatures?

Something very weird about that.  I've experienced cold sensations before, along with something that felt like it was brushing up against my hand.  But I've never felt a "heat" spot.  so why is it that this happens?  Can ghosts or spirits be cold and hot?  or are they two different types of spirits?

I don't know what to make of that.  Maybe the heat signatures are real people?  or maybe a cold spot is just what it is.. a cold area of the room that has nothing to do with paranormal, that it's just a draft or a colder area of the house.  Maybe the real spirits give off heat.  In human form, you give off heat, so why not in spirit form?

Now, speaking of spirits,  we've just finished up our investigation on the 6th of this month.  Some weird things happened but i'm not completely sold on the paranormal legitimate side of it.  I still think it has much to do with other factors in play but I am not at liberty to discuss that at this time.  Needless to say though, we did catch some audio that can not be explained and seems to point to intelligent style haunts.  Again though, i'm not 100% sold on that just yet.

I'll let you know.
