As a child growing up used to believe, very convincingly that I could fly in my dreams. I flew above my house as young as three. I could and still can recall what the roof of our house looks like, from being three! How can a three year old know what their roof looks like, I mean shingles, along with the additions my Dad built on to our house. I could see this as a child, from above.
The older I got, the farther away I could fly. In high school, I flew any and everywhere I went as a teenager. I loved it!

It was a wonderful free feeling. I have tried it as an adult. Not able any longer. Except only once. I flew, as an adult. When I did, I was back to the house I grew up in, I was flying over the tall tree in our front yard, in the clouds. When I went lower, I could see my two little daughters on the ground, unable to fly with me. Reaching out to them, realizing they couldn't come up there with me, I no longer wanted to fly. I couldn't see them when I flew above the clouds, and that bothered me. So from that night on, I never flew again.

Now my daughters are over the age of 19, both have moved out and are on their own.
A friend told me I was really flying, not dreaming it, and I felt relieved, as it was so very real to me. I have tried to do this as an adult, but am not able to do this any longer.
A few years ago, I shared this with a friend, who said I was really flying, I was asrtoprojection, having an out of body experience. It was always so real to me, that I believe this.
I so wish to fly again, any suggestions on how I can do this once again?

I was doing that about a year ago.
I think a lot of your ability to do it, unless you know how to control it, can depend on your body chemistry. Like when your body is full of junk food your arteries are slug and you are sluggish. When I was doing that I had switched to sea salt and olive oil and cut out the junk food. Also the less materialistic and caught up in your problems the more you can 'let yourself go' too.
At least that is my theory on how I was able to do it.

I really don't understand OBE and astralprojection. From what I understand you leave your body but what I did was have a sense of being there and looking down but I really do not believe I left my body like OBE/astralprojection.
