What does it mean if you're awake, but it feels like you're dreaming?

It is a mistake to think that your brain is at a low level of activity during sleep. It has been found that the brain is more active in dreams than in some states of wakefulness, with the exception of certain neurons in the brain stem, which are related to attention and memory. These appear to rest during REM sleep. But in general the nerve cells in the brain have continuous intercellular communication
Sometimes when we are trying to solve a problem, the solution comes to us during sleep. This may reflect that not all sleep consists of dreaming. A portion of it is thinking.
You may need to get good sleep to rest your brain.
