What could this be? Is it a medical condition?

I've had those feelings, sensations, they are normal. Hyper sensitive, when I was a teenager, sometimes I would feel really tall, I'm 5'3", strange, funny feeling. or other times it seems as if you are one with the world, kind of an all knowing feeling, but no words for it. You'll outgrow your anxiety , don't let that be something you carry with you all your life. It's normal to be anxious in some situations or nervous. It's a new 2000 diagnosis that is normal for everybody so the Rx can get money/meds to people who have a normal situation. May have super sensory sensation, If it's all the time and you suffer hearing loss or other measurable sx, then get seen. I'm sure somebody will name it for you. Sounds pretty normal to me, Have you had deja vu experiences, yet?
