I'm seeing things that are not present in reality. I saw pink tablet on my fridge. Then at table and after that at bed. I asked my mom she told nothing's there. And after some time nothing was there.This has occured sometimes earlier also. But the last day it happened 3-4 times. I also saw very big pimple at my hand and chest. After sometime it disappeared. I felt that my father scolded me but that's not possible because he was sleeping and he  doesn't talk to me even. At night I also experienced seizure.after 5-10 sec it became normal. I even experience nightmares which I'm not afraid of now as it's quite frequent I'm unaware what is this and what to do to control it. pls guide
