Is it normal that i see little cartoons everywhere when i'm high

Everytime I smoke weed I see cartoons. Yes I know some of you think its derealization/depersonalization ; I know about that , its when everything around you doesnt feel real and you may have panick attacks. But anyways my problem is whenever I'm high and I stare at the grass or the wall , little cartoons seem to pop up . and the more I stare at it the clearer it gets. It gets worse and worse because the picture keeps getting bigger. Yesterday I saw these cartoons at school , I took out a chalk and started tracing what I saw on the board ( we had a sub ) I was drawing cartoons. & normally I cannot draw to save my life. The next class I had I started seeying cartoons again , so I started tracing what I saw in my notebook. The WHOLE page , was literally filled with little cartoons and the class was only 45 minutes long. I dont know how I drew all of that , the cartoon was goofy and I've never seen it on tv before and I kept trying the same character with different face expressions. At first seeing cartoons was fun , it wasnt until I told my friends and they had no idea what I was talking about. I looked all over the web to see if anyone else feels the same way and I couldnt find anyone
