How do you stay long enough to explore?

Hey guys, so I started trying to astral project a few years back, I could never stay still for long enough so it never worked. But then I decided to try some guided meditations to help me keep still and to give me ideas about how to do it myself in silence.

To keep a long story short I have since managed to do it. Only 6 times, but every time I do it I'm zapped back into my body, I get around 2 minutes. Is it because I'm too excited? I have left and floated above myself, SEEN myself with my eyes closed and watched my chest rise and fall. Then woke up (vision was like looking through a steamed up window) (I have had 3 experiences just like this.) one experience I left my body, felt so excited! then just went down into darkness and kept falling and falling and then I was back into my body.

My 5th time I was sitting upright meditating and I stood up when I felt the tingles but my body was heavy so I tried to jump to float (because I'm usually floating) but I fell onto my ass instead. I prepared for pain but there was none, so i done a hand check and they were transparent with fingers I couldn't quite count. I wasn't sure if this was real life until I fell and didn't feel the pain. And then the last time. Today, I'm laying on my sofa after some meditation, I feel the tingles and get up quickly, I stood and watched myself briefly its a really sunny day but in my astral the world had a bluish hue. The colours were dull. It was the clearest I have ever seen the last two times I have successfully done it. But then I wake up! Too fast I don't have any time to explore and it's so annoying! I initially tried this to see if it was real. It is real. I know it is! But now I want to play and I can't because I keep being sent home.

So.. Any tips Appreciated x
