Imaginary visualiasian or Astra projection?

I am a complete beginner in this. It is my fourth day when I am trying to experience Astral Projection.

So far I am not sure whether I visualize it or it is an astral projection.

I am able to see my both hands and control them a bit. For example move around fingers or arm. I can Also lift and bend my legs. My arm and legs are very bright and background is black. I do not see anything else just my arm and leg. Neither my physical body.

I am able to feel some warm or vibration mostly in my left arm especially when I tune in my left arm it is not that much vibration on any other body parts. Other sign I have developed that randomly any body part nerve twiched sometimes.

I have tried few times binary beats which didn't really work out but I know It need some practice. The best works so far is on my own when I lie in bed at night and tried for hour all I achieved is the hand and leg described above. Or with expert hypnotic audio designed for Astral projection with this I feel more relaxed and like in a deeper my self. I have neither any fear or thought in my mind in any condition when I am learning how to astral project.

I have looked several ways of exiting my body and experimented whit this hand I am seeing:
- Rope, climbing up and imagine the feeling and using legs to help pull my self up
- Think of the solid object in my room and hold by it to pull myself to it.
- Imagine that I am rotating my astral body inside my body.
- Roll over my astral body.
- Looking in my back eye.

I have heard that I need to learn Kundalini and Chakra. That could help me to astral Project. Any thought of this?

This hand and leg I am seeing is astral or imaginary body?
