Do you think your character can have a dream Of course! My character have a dream...
To have a dream in your harvest moon, you these things:
1. It is suppose to be Winter 30 (any year)
2. Sleep at 9 PM or sometimes straightly 6 AM
Then your character will have a dream. 3 sure dreams your character can have, once a year
your chracter will only have one of the three dreams.

1. A battle with Karen (included in this dream : Mary you and Karen of course!)
2. Unwanted marriage (included in this dream : Mayor,Carter,All harvest sprites and you)
3. Harvest Sprites Secret (included in this dream : you, all harvest sprites and gourment the judge of every cooking festival)

After any of these three dreams, your character will wake up and will say this line :
"Dearm" (suppose to be dream) "Oh well back to sleep"

And then somewhat my character and Karen seems to hate each other.... 0_0
And I thought that could the dream is true (sometimes this two lines won't exsist)

And another lot bitter for you especially if you have a lot of money :
If a wild dog touches your character, you will collapse and then wake up in the clinic, then all of your items (except tools,rings and power berries) and money IS GONE!!!!!! You will be terrified! ( Wild dogs appear starting 8 PM )

I hope I help you somewhat...
