Was this astral projection?

Was this the beginning of astral projection? Bare with me I will eventually get to the astral projection part. I had another extreme meditation yesterday morning. I feel bad because I was trying to meditate for someone else and then something else took over. Everytime I would get the feeling that I was deep enough I would feel a giddy feeling in my heart, then all off a sudden it felt extremely intense, actually beyond intense but not uncomfortable. I felt this feeling enter my heart and then sort of spread me heart open (not sure if this is a good description) then it kept growing and growing and growing and spread wider and deeper and then I felt go all the way to my back then right through my back, almost as if I was glued to the bed with the opening pressure. That is what it felt like an opeing I suppose. I can't decide if this was more intense then the pressure that I have head in my head or not. I they are each their own. Anyways all of a sudden I felt a huge lump in the right part of my chest (huge) I can't describe it. Maybe like when you swallow something and it is stuck, but bigger. I heard in my head blockage, so mentally I started pushing the blockage up my through (then I actually felt it in my throat!) then up through my throat and i felt it release out of my mouth. Then it started again, and i continued to do this for a bit till the blockage in my heart was gone. I felt so light, like a huge weight was lifted off my chest. I have felt nothing like this so far in my meditation. I know it was a healing, and that I need quite a bit in my heart but I wasn't aware it was that much. It was intense.

Ok now for the next stage of my meditation. After that I was laying there and as usual I felt the huge vibration and tingling. Then all of a sudden the vibration and tingling became extremely intense all over my body. Then I got tingly cold, and I felt as if I was floating, not physically but inside my body. Then all of a sudden it got beyond intense then boom, I would feel myself come back from somewhere that I was unaware of going. Not sure where. I think this tingling was a little too intense for me, wasn't quite ready for it. I did this over and over and over. I finally pulled myself out, a part of my had to go to work and the other part was a little afraid of what might happen if I layed there longer. I think that this was astral projection, but it might be something else. So if anyone else has any ideas I would be happy to receive them. I was very suprised when I came out of meditation to see that I had only been in meditation for thirty minutes. It felt like a lot more than thirty. I dicided to just sit for a few minutes with my eyes open and then I got a huge tingly sensation in my head and I allowed it to take over for a bit and let it have its way. Then i closed and said my thanks. I was sure to ground my energy for a bit before I went back out into the living room. Happy for my experience though and very thankful. Like I said though, I was trying to receive messages for someone else and feel bad that something else took over and I didn’t receive any real messages. Was this selfish of me because I allowed it to take over?
