Am i sleep walking or what?

a week ago we found the main door opened. like someone tried to come in but the chain wouldnt let the door open so it was left opened, and also there was a piece of aluminum foil cut out. it wasnt me she thought it was me because well i smoke weed. and then 2day this morning i slept in myparents room bcuz my room got too hot and i left the door opened, it was closed in the morning and some1 put water in the trashcan. half way. and last night i stepped on the trashcan by accident and there was no water but a bag. whats going on??!?!?
