Yes. In fact I just discussed this with a member here recently. My first was when I was somewhere between 11 and 13. I used to work with my step-father who was a plastering and drywall contractor in the summer and on weekends. I was riding in his truck on the way to a jobsite on morning going down the Kennedy expressway in Chicago looking out the window at the buildings, the traffic, the El, when suddenly a feeling that to this day I cannot describe accurately came over me. It was like I was familiar and intimate with everything...the people, the buildings, the whole environment...felt like it was a part of me...like it was as familiar to me as my immediate family or my reflection in the mirror. The feeling only lasted for a few seconds, but it was definitely something I had never experienced before.
I used to do yoga using DVDs as a guide, but became disheartened when I didn't see a measurable improvement in flexibility or strength in a year.
I meditate daily, often more than one session per day. I meditate anywhere between 20 minutes to an hour depending on how much time I have, and typically fall asleep to yoga nidra.
