So unknowingly I took weed. While coming back to my home I was riding my motorcycle and suddenly felt like everything is unrealistic. I felt like I am dead. I am seeing my past in front of my eyes. This incident took place 6-7 months ago and slowly slowly I started feeling like above mentioned problem everyday. I feel like I have become emotionless. Everytime feeling drowsy. No mood swings. sometimes I feel like I am dead and whatever is  happening is totally unrealistic. Please help doctors
