Several verses suggest Satanic, and therefore possible demonic, on-going active. Ephesians 2:2, for example tells us of evil oppression among the sons of disobedience. Then we find Acts 5:3 where Satan has "filled the heart" of Ananias. We are for sure in a spiritual battle with the forces of evil. But to claim this still includes possession has little support. But we cannot rule it out either.
Then there is nothing I can do for you. Nonetheless, I have witnessed possession many times.
