Passages?

love-sex-aging

OK, I need help interpreting the illustration:

  1. She’s single and sleeping alone. Courting suitors?
  2. She’s married. Shares her bed.
  3. She’s married. Shares her bed with another.  Their child.
  4. The family gets a dog. Dog sleeps in bed.  Less room on bed. (This is all sounding close to home.)
  5. She’s pushed out of bed by husband, child and dog? Further separation?
  6. Empty Nesters pull together?
  7. She’s alone. (Husband deceased? Divorced?) Finds peace in meditation and being alone?
