Nice story but ultimately not believable.

First, who puts a ton of rocks in their living room? Nutcases most likely

If Sasquatch can go upstairs and dig around in the clothes, why didn't they just take the rocks back?

Sasquatches aren't psychic. If they were there's be no need for them to ever watch you, let alone chase you.

They don't give those kind of gifts for another thing.
