I dream a guy gave me a white rose

It means you dreamt a guy gave you a white rose. Most of the time dreams don't mean anything.

It means that you will be wearing a white dress at your wedding, so be a good girl and remain chaste. It also means that the love of your life will arrive on a white horse, to sweep you off your feet.
This love will last until the first white sale you attend, where you will meet and fall instantly and madly in love with a muslim man dressed all in white. Unfortunately, under all that white cloth is a suicide vest and the last thing you see is a flash of white as it explodes.
Anyway, I'm pretty sure that's what the white rose represents in your dream.

It means you're pure and innocent

It's not the dream itself you need to interpret it's how you felt when you woke up from the dream: works nearly every time for me and has done for years.

rose=love, white=pure, red rose= sexual or romantic....white rose= love but friendship

you love some guybut are not real hot for him, but you love him so much you may still marry him

Sorry hun can't help you.

There's a book with different dream meanings, I'm sure you'll be able to look it up in the internet. If not, look at the Freud book: The Interpretation of Dreams.

Greetings

I don't know what your dream means, but this is supposedly what white roses mean.
