UFO Sighting in Halton Hills, Ontario – Blue indigo lit disc appeared at the edge of my bed suspended in the air, diffusing the light in the room; disc divided in 4 quarters each quarter

A disc with approx 15 inch diameter appeared in my room, around midnight. the disc was divided in 4 quarters, each quarter had signs i didn't understand. i only remember part of them an equilateral triangle, a dot next to it. the bottom right quarter had a sinusoidal line. the disc was suspended in air, not moving at the edge of the bed directed to my eyes and forehead. i got scared but instantly felt peace and fell asleep. i cannot remember all the signs or language...So i can draw the complete picture
