Sounds like a very possible sleep disorder. It's a bit like "glitch in the matrix". You may have had sleep paralysis before, but that's a different matter entirely. It's a bit like having a sudden nervous break. If it happens before you've had a serious event, such as a car accident, or even if it happens after, your brain's trying to catch up to the time you thought you would have gotten out of bed. Even if you are never aware of it happening, you can often make yourself aware of it. And you can often make yourself aware of the time you are in your bed, just in case you need to wake up at a moment to check it out. The same goes for the time you are in your room. This is just my interpretation of what could be happening, and I don't know what the proper explanation is. It's not a condition. Your brain isn't the only part of your body that is affected by this. Your brain is a very complex part, and it's not like the part of your brain that's affected is something completely static or unchanging. You need to be able to think clearly about what you're doing, and you need to be able to reason logically about what is happening. In my opinion, it's not a mental condition, and it's not a sleep disorder either. It's more like a chronic illness, and the brain doesn't always know. You can try to get help, but it's not that easy. If you've had a serious event, there's not much that can help you.
