I was drilling four holes to mount an Amazon device. When I drilled the top right hole I felt a little resistance but pushed through and it went clean almost like nothing. The bottom right hole kept bouncing so I stopped. The anchor in the top right will only go in about 90%. The anchor won't go in the bottom right as it isn't deep enough but when I push the drill bit in the bottom hole the top anchor moves. I can hear like a kachunka noise as well. I flushed all toilets, ran all water, turned on all lights on area including outdoors, and plugged something in the outlet near it and ran it. Nothing seems to be happening but I am sure I hit something. How can I know what it is?
