A phrase to describe a "collection of false exaggerations"

I am looking for a phrase to describe a "collection of false exaggerations", something that can fit well in the following line:

I am really shocked to see this, it seems that everything you told me before was just a collection of false exaggerations.

I don't think "collection of false exaggerations" is a real phrase. "Bag of lies" is a similar phrase but not with the same meaning.

I am looking for a phrase that can directly replace mine in the above sentence or otherwise any other way to say the above sentence while keeping the feelings same. The feelings here being that my expectations were set too high due to a lot of exaggerated information fed to me.

The term hyperbole means

extravagant exaggeration (as “mile-high ice-cream cones”)

It does not necessarily refer to a collection.

You could create a phrase such as a plethora of hyperbole, or some such.

(Or even a hurricane of hyperbole.)

As Andrew Leach comments, the standard idiom (informal, primarily spoken not written) is...

a pack of lies - a completely false story, account, etc.

Tall tales are fanciful and elaborate stories, often highly exaggerated. The phrase specifically refers to American fables that explain the natural world, but is also used by analogy to describe more mundane exaggerated stories. Or as an indirect way to say someone is lying.

A fish story is an exaggerated story that glorifies the teller. It refers to boastful claims by anglers that they hooked a "big one that got away".
