[00:00:00]Ever locked your door, then checked it again?

[00:00:03]That feeling isn't forgetfulness. It's your brain seeking certainty.

[00:00:07]Your brain has a safety system driven by the amygdala, which constantly scans for danger. When you lock the door, the action is quick, but your brain doesn't fully register it. So, doubt creeps in.

[00:00:19]Did I really lock it?

[00:00:21]This is called memory uncertainty. When your brain isn't confident in a memory, to feel safe, your mind pushes you to check again. The second check gives your brain stronger proof, calming that anxiety. It's not weird. It's your brain trying to protect you.
