I have had many experiences since i was a child. I would often astrally project out of my body and go to places.I was scared back then to understand what was happening to me and i decided to block my memory which happened to cut my contact with them.
It was not until many years later (When i turned 20 and afterwards when i turned 34) that i started to see them again. I have had many experiences now where i could remember with whom i was talking to,or, seeing ufos fly nearby.
I do not think that we are alone. That this is the only universe where life as we know it could possible have materialized. I believe that there are other dimensions, based on different frequencies. Frequencies that only few people or people who are prepared can access and understand what they see. The human body has not only a physical body, but, also an emotional and spiritual body.
If your bodies are not aligned your life will pass by tough situations, on the contrary, if it is aligned, you will live happy, in peace, and be able to "see" the different dimensions and frequencies i mentioned before.
