All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
Our advice to you is to ignore these whispers, neglect them, and not pay any attention to them.
You should not judge that something has become (ritually) impure just because of doubt. Rather, you should act according to the principle, that it is pure.
You should act according to this principle unless you become absolutely certain that it has become impure; certain to the extent that you can swear that it is impure.
If you become this certain, then purifying the impurity is easy; this is by pouring water on it and then immersing it all with water.
All what you have mentioned is nothing but baseless whispers. So ignore them, neglect them, and do not pay any attention to them, because giving in to them leads to a great evil.
Allah knows best.
