Grandpa's last laugh

To say my grandfather was eccentric is like saying water is wet – technically incorrect, but close enough that nobody really cares. I suppose in lieu of a better word "eccentric" will do.

In any case, my grandfather was a writer, as well as a puzzler… and a prankster. He loved elaborate, drawn-out pranks for no particularly good reason.

When we went to execute his will, we found a strange note hidden inside. Here’s what it says:

Of course, you will all be wanting to know just how to access all of my belongings so that you can divide them up. Not to worry! I have all of my possessions in order at the bank. All that you need to do is to provide them with the correct password. Quite simple, really. But since I love having the last word, I’ve made it a bit of a challenge for you all. All you need to do is to solve a word web. Oh, and you’ll need page 14 of my latest book. Good luck!

I looked up a word web, and found this question here on Puzzling.SE, which explains how one is solved.

We then went and opened up his book to page 14, and this section was highlighted:

The air was filled with buzzing, and not the pleasant buzzing of bees – but the obnoxious drone of flies. It was a horrible day to go out. And truth be told, I wasn’t exactly sure why I had decided to travel. I had gotten the urge to take a walk, and now I was regretting the decision – what with the cold, and the flies, and… oh, Lord.
I squinted at the object lying on the trail in front of me. It looked vaguely like someone had tried to grow a cactus, somehow managed to fail, and then tipped over the pot. In any case, a spikey tangled mess now blocked the trail ahead, and there was no way over (or, for that matter, under). And now the wind was beginning to blow.
Sighing, I turned around, zipped up my sweatshirt, and started heading back. It was a twenty minute hike back before I reached my house and walked in. Defeat in something you’re not sure why you started is a surefire way to feel down. I like walking, but it’s not really something I love.
That night, I had a strange dream. I don’t normally dream, so a dream in of itself is unusual, but this was an especially weird one. It was bright, and I could see the sun. I was squinting in the bright light.

But… this looks nothing like a word web! Could you help me figure this out and figure out what my grandfather was on about?
