You may visit someone dear to you who you haven't seen in so long. Fill it up with as much detail as possible. You may want to meditate with a partner and let him or her guide you in focusing on a special theme. Whatever is important to you at this time in your life. When you're ready, allow yourself to come back, opening your eyes when you feel comfortable doing so.
Some people choose to meditate for a given period of time.
Sometimes there's a signal symbolizing the close of the meditation, like a bell. My own experience has been that when I meditate in the morning, I have a much better day- more flowing, less tension, more clarity. I'm faced with. Sometimes I feel like I don't have time to meditate. And that's ok.
