Here's one exercise I do as part of my Tai Chi training that is very relaxing. I lie on my carpeted floor, face up, legs slightly apart, arms beside my body, palms down. I use a yoga mat for extra comfort and place a thick folded towel under my head to keep my neck straight.
I focus on my breathing, eyes closed, and imagine I'm gently sinking into the ground. I plan to use a timer in future because I almost fell asleep the other day!
