Can Orbs Be Negative?

In the past I had never given any thought as to whether or not orbs could actually be bad or negative in nature. For some reason, I've always just assumed that if they weren't dust, pollen, etc. then they were positive energy. However, I've had to rethink that position recently based on an experience during an investigation.

My investigation partner Diane and I were walking around the various rooms taking the standard control photos. As we approached the master bath Diane suddenly hesitated and was reluctant to enter that area of the house. She felt there was something negative there and was feeling very uncomfortable about it. If you've read my previous posts you will remember that Diane is psychic so when Diane makes a comment like that, I pay attention.

Diane wouldn't enter the bathroom but I felt it was important to take some pictures if she was feeling that there was something there so I went into the area and started to shoot away.

The first pictures of that area that I took were of the bathroom closet. As you can see, there were some unusual results. These photos were taken one right after the other and are shown here in sequential order.

So the question is, how can we know if the orbs that we are encountering in our photos and videos are positive or negative in nature? Outside of specific feelings we may experience like Diane did, I don't know. The question begs for some sort of experimentation to be conducted to see if an answer can at least be hypothesized.
