My boyfriend keeps talking about an episode (or movie, I have no idea) about a day Charlie Brown is having and everything is FINALLY going good for him. Then at the end, he wakes up and realizes it is all a dream.

Can anyone help me with the name of this Charlie Brown episode? I am pretty convinced at this point that it is a dream MY BOYFRIEND had. :)

I know this is an old thread, but it may be "What a nightmare Charlie Brown" from 1978. Snoopy is sleeping on his doghouse outside and dreams about being in the old West and being part of a team of sled dogs. Near the end, the sled breaks through a frozen lake, and Snoopy attempts to rescue the team. Just before he drowns, he wakes up, knocks on the house's door and Charlie Brown answers, Snoopy mimes his dream and Charlie Brown lets him in. Snoopy makes himself a sundae and goes to sleep in Charlie Brown's bed.
