I just meditated for the first time yesterday and I'm not sure if I got into meditative state or fell asleep in the middle of it; all I know is that nearly an hour went missing from my time and I was drowsy when I "came to"(for lack of a better phrase). Afterwards, I took a nap, but I wanted to know if it's normal to accidentally fall asleep during meditation, especially the first few times. Also, as part of the early part of my meditation, I focused on a happy thought for a short while, that happy thought was my boyfriend, and my heart rate sped up noticeably; I could really feel my heart moving fast and hard. Is this a normal early meditation thing or was it just what I was thinking about that caused this? Don't worry, I didn't have a heart attack or anything, but once I moved on to focusing on breathing instead of my boyfriend, my heart started to slow after a bit. A little after this is when I opened my eyes and realized I had no memory of the past hour. Is any of this normal? Can anyone help me to somehow explain some of this or just give me a new perspective?
