Lake of Sacrifice

Months ago I had a dream a friend took me to see this lake. When we got there, two elderly men, visibly twin brothers showed up after us, one of them dropped himself into the lake and never rose from the water. After that, his brother that remained on the deck got younger and left the place in silence.
I knew my friend had told me about that place before, which she never actually did in real life.
Crazy dream, but inspired me for this art!
