Whether you wake up confused or refreshed and ready to go depends on in which sleep stage you wake up in (light, REM or deep).
If you wake up in REM, you’re going to be slightly confused.
If you wake up in deep, you’re going to be completely confused and feel very bad until the end of the day.
If you wake up in light, just before starting to fall in deep sleep, you’re going to feel refreshed, and ready to go.
When I need a nap like this I use an app that detects my body movements (using accelerometer) and wakes me up roughly in 15-20 minutes at the right moment when the sleep stage is the lightest. Here is one such app for iOS.
