Can we draw the following hypothesis from the context?

Context:

The Longest Nap<br>Tom was tired from work. He decided to take a short afternoon nap. Tom didn't wake up right away. His nap turned into a long sleep. Tom slept straight through the night.

Hypothesis: Tom wears his mother's old housecoat to nap in and it's fuzzy warmness makes it hard to wake up sometimes.
It's impossible to say
