Play the street address # of either of the schools... also the number four as a Bonus Ball because you mention "four" children and also buttons which sometimes have "four" holes in them. Buttons have holes and dishes are round and so is zero, so "40" is also good or any number ending in "0". Maybe even "10" because ex = "X" which often represents "10". Schools usually have 8 periods a day so use the 8. Also I don't remember what was Catfish Hunter's uniform #? Include that too. Toss in the day's high temperature because of the weather component.
Also, I have a question. If a dream can predict a lottery drawing (since the same set of numbers comes out for everyone but the dreamer has the privilege of the prediction) what mechanism is involved here? Future events can be altered by the slightest things so there must be particles like tachyons that flow backward through time from the draw machine and enter a few people's brains which are somehow equipped to detect tachyon signals sent in morse code that translates into numbers but which the mind during R.E.M. sleep forms into more everyday images as dreams. Running unclothed through a (hopefully unoccupied!) high school in a dream is more "fun" to the brain than seeing the school's address number hovering in an otherwise empty void.
