weird..o.o'

i created a character and drew it this morning..but, i cant stop seeing it everywhere i go, just like a ghost o.o' i was like "wow whats happening to me?!"..i don't really know if that's normal because this is the first time that happens to me, i asked my dad (he was drawing before) he 発言しました it can happen, and asked my sister (she draws too) she 発言しました its not normal! o.o..P.S: i slept and when i woke up i saw it again, i brought a pencil and a paper and i found myself drawing it again o.o'..is that normal?
