Is there any evidence suggesting that thoughts or experiences from late in the day are more likely to be dreamed about the following night compared with similar experiences earlier in the day?

The probability of what you'll dream is really dependent on a ton of factors. Stress can harm your ability to remember, and process, your memories during sleep. If you are highly stressed due to hunger later in the day, you brain may be more likely to process the memories of events before hunger set in. However, the opposite may be true for others. schizophrenics for example, have problems with how they process memories. Our brains can accidentally be configured to process memories in an atypical/unhealthy way. Also, extreme time-dilation can affect us. Personally, while in basic training, we got a lot less sleep than I was used too. I started noticing that the days seemed to blend together, and time moved quicker. My dreams, during that period, never seemed to follow any pattern based on time that I can remember, and it's likely true for most people in similar situations.

This study looked into how alcohol affects memory storage: http://pubs.niaaa.nih.gov/publications/arh27-2/186-196.htm
Obviously there are many things besides alcohol which can affect your ability to form and store memories, so taken together, all of these indicate that the order of the events of our day, processed in our dreams, is affected by how you formed those memories while actually experiencing them awake.
