Hi everyone. Throughout the latter portion of my life so far (currently 20) I've had moments where it feels like I'm in a dream or watching my life happen outside of my control like it's a TV show. Usually its doesn't happen enough to bother me, but this past weekend it happened a lot more than usual and seemed a lot more severe than usual. 

For instance, I was at a party with friends and all of a sudden I didn't feel real anymore. People would say things to me and I couldn't understand them, but somehow I also DID understand them because I replied to them and held a conversation with them, but I couldn't understand what I was saying either. But I still kept talking to them without actually processing anything that was going on. It was like I wasn't actually in control of anything. Things felt numb, and even when I tried to ground myself and tune into my senses it didn't seem to work this time.

Normally it doesn't get that bad, and it's happened a lot more than usual in the past few days... is this something to be concerned about or do I just wait for it to go away..? And if I should be concerned, do I tell my doctor or my therapist..?
