Galadriel’s mirror

[MLD-Grounds-Keeper-Willie]

It shows a bunch of things.

'Here is the Mirror of Galadriel,' she said. 'I have brought you here so that you may look in it, if you will.'
The air was very still, and the dell was dark, and the Elf-lady beside him was tall and pale. 'What shall we look for, and what shall we see?' asked Frodo, filled with awe.
'Many things I can command the Mirror to reveal,' she answered, 'and to some I can show what they desire to see. But the Mirror will also show things unbidden, and those are often stranger and more profitable than things which we wish to behold. What you will see, if you leave the Mirror free to work, I cannot tell. For it shows things that were, and things that are, adn things that yet may be. But which is t that he sees, even the wisest cannot always tell. Do you wish to look?'

So, in answer to your question, it can, but it does not always do that.
