Somehow I received a text message to open the door and call the police.

Maybe you met a telecom fraud message. If there is a short message link website on it, don't open it at will, because it is likely to be a criminal fraud website. At this time, you need to call the police station at the first time to verify and confirm. If it is really a case investigation message sent by the police station, you need to go to the police station in person to cooperate with the public security organs to ask about the case.
