Question: When Richard's parents are building the treehouse, are the facts Richard states about accidents on ladders and trees true?
Question: Was everything Richard Tyler went through real, or was it all just a dream?
Answer: It's hard to say for sure but I think it was just a dream to help him to overcome his fears.
Answer: Some facts about accidents involving ladders and trees while he's talking to his father as they build the treehouse. He talks about how dangerous ladders and trees can be, which is a reflection of his cautious and somewhat anxious personality at the beginning of the film. Although Richard's exact statistics or facts aren't fully detailed, his concerns about safety are valid in a general sense—treehouse construction and using ladders do come with certain risks if not done properly, such as falling from a height or sustaining injuries. However, the exactness of Richard's claims (like any specific numbers or details) is not the focus of the story; it's more about Richard's growth from somebody who is fearful to someone who is brave enough to face his fears during the adventure that follows.
