I may come off like a retard, but has anyone experienced a psychic like ability to determine when they wake up? I know it sounds like like /x/ than /sci/, but I've experimented with this in the past, and just "thinking" and wanting to wake up at a certain time has lead me to doing so. I've had times when I "thought" about waking up at 4AM, and then I would. It wouldn't be 8 hours, or even close (more like 4) and I wouldn't feel fulfilled at all, yet I wanted to wake up at the time and I did. Are there any studies on this?
