The time between being awake and falling asleep is known as hypnagogia, a transitional state where you may experience vivid sensations or hallucinations. This period can vary in length but typically involves a gradual shift in brain activity as you drift into sleep.
This image came to me during that time. Not exactly this of course but the seed was planted.
It's finished, framed behind glass and will be part of an upcoming exhibit. 15 " x 22".
