Turning 74 the day before Thanksgiving and the cosmology of Earth

So here I am having actually made it to 74. My younger wife seems to think that I will last many more years. Well maybe with a lot more medical attention; cardiologists and endocrinologists that is. In the meantime I consider the cosmology of Earth as relates to other intelligent races in the universe and it's many dimensions. Why am I here and where do I fit into the scheme of things? I seem to have dim memories from early childhood of flying through the air. It is chilly and I am scared. Is this an abduction memory? Thinking back I remember mentally constructing a brickwall between myself and whatever the perceived threat was that prompted the need for such a construct. As time evolved I expanded my wall to completely encompass myself; such was the need for security in my juvenile thoughts. I also had dreams of lions and tigers roaming  our house and having to hide under the front concrete steps. Now some 65 years on the paranoia has weakened but remains in the darkened recesses of thought.
