Those lights could most likely be dust. Alot of dust lights up when a flash is used in pics. The cold she may have felt is that huge window behind her. What was the temp outside and does the window leak air?
Another photo from same investigation downstairs near the light... (shortly before this the K2 meter in the middle of the room picked up a small response to some questions i asked)
Strange white orb on investigation... Lead Investigator felt really cold when she stood up... have a few more from this.... same strange orb appeared in living room after EVP session downstairs... thoughts? Is it a fly ?
