First attempt

Hi, I’m new to astral projection. Yesterday, I tried it for the first time. I lied down, relaxed my body, and closed my eyes. I stayed completely still for a good amount of time. Eventually, I began to feel as if electricity was building up in my legs and slowly moving up toward my head. I started picturing myself getting up without actually moving my physical body. The next thing that happened is hard to explain, it’s as if my eyelids became transparent and I could see the walls around me where I was lying. But it felt like my vision was coming from where my feet were, not from my head. I ended up losing my concentration and moving. When I checked the time, I realized I’d been doing this for close to two hours. Has anyone else experienced something like this? Is this a good start for a first attempt? Any advice? Has this happened to anyone else, or something similar? Am I on the right path?
