I started meditating maybe 2 weeks ago. I really enjoy it. It seems to left up my general mood and self awareness. I am doing a very basic meditation. I do the following:

1. Light a candle (not sure why, I just do).
2. Sit with my legs crossed, up on a pillow so that my hips are higher than my knees.
3. left hand ender right, in my lap, thumbs touching
4. Eyes sometimes closed, sometimes half open, not sharply focused
5. I merely focus on my breath. Inhale and exhale through the nose.
6. When a thought pops into my head, I let it pass, then come back to my breath.
7. Sometimes I will use my awareness to scan from the top down of the left side of my body, then from the bottom up on the right side.

My questions are:

1. The candle starts flickering generally once I get focused on my breath. Any significance?
2. One time and one time only, I saw a crisp, clear, small red dot when I closed my eyes. Any significance?

Thanks in advance for your replies!
