I often send notes to myself as e-mails. I got an e-mail from myself last Friday at 8:52pm, a couple minutes after I parted with a couple friends from work, and a few minutes before I boarded a Caltrain.
The note said just: Clearness.com
I have no idea what it means.
I figured it out. A friend had recommended a musical artist named Clare Means, who has a website claremeans.com, which my android device auto-completed into clearness.com.
So my subconscious self isn't planting notes to myself behind my back. Phew.
