It's possible, but any decent wallet will give you a warning or even won't let you send because that the receiving wallet address is yours.
It's uncommon to send to your own address for whatever purpose it may as it cost a transaction fee.
Here's an example on mycelium mobile wallet

What if I mistakenly copied a wrong address that doesn't exist, will the transaction be cancelled just as a bank would do or the transaction will be successful.
Since you are using an example from banking, I think its good for you to know the main difference. Banks rely on accounts to identify users, so sending money to your own account number triggers a flag because the system recognizes it as the same account. Bitcoin wallets, on the other hand, use transaction outputs and addresses to track funds. Sending bitcoin to an address you control, even if its from the same wallet, is perfectly valid and will be broadcasted to the network. The software is designed so that no one can stop you from sending Bitcoin to yourself, even if its to the same wallet address. And there is no intermediary involved.
Some wallets use different colors for addresses that belong to your wallet to help you keep track of them.
Wow. The structure's existing in the system are really nice then. Since it is back to your personal wallet address. You won't have to cancel the transaction and start over again because you copied your own wallet address by mistake just as banks will make you cancel the transaction until you get the account right.
