I've been reading some books about astral travel, going to astral planes and in some books say that while dreaming, we go to some sort of astral plane. I don't know if this is correct, but i've been wondering what could happen if i travel to an astral plane while lucid dreaming.
Last week i had an experience on a lucid dream. Inside the dream i said to myself:
-"I want to go to an astral plane, meet astral beings."
I looked up and jumped. I began to fly very slowly. I must have levitated just a bit. I decided to look at the ground and concentrate on seeing the ground further away. It began to work, i flew a little higher until the Earth has disappeared. Everything was dark. It seemed i was in space but everything was black. Then I saw a dot, a little light. I decided to go to the light. I concentrated on going there, but it was difficult. It seemed to take about 2 minutes and was still on the same place. Then the light became a little bigger. Suddenly, it began to form a tunnel. It looked like a spiral wormhole approaching me. In the middle, there was a silver cord as mentioned on astral projections. I started to enter the tunnel. I felt anxiety and my heart beating faster. I began to watch my hands to not wake up. But it did not work. I began to see the tunnel to walk away and I came back to Earth. I woke up with my heart beating at "1000 bpm."

What do you think? Do we go to an astral plane during dreaming? Did i have an experience on traveling to an astral plane?
