Right here's the story...

I have medium brown hair and decided to go blonde for a change ( I don't normally dye my hair). So my friend prelightened it then dyed it blonde but it went wrong and came out strawberry blonde/ blondish. And now my mum is demanding that I dye my hair back to its normal colour! But is that possible? Please help

The only way you can get it back the way it was naturally is to chemically remove it but honestly, you do NOT want to do that because it messes up your hair and damages it and it takes a loooong time before its healthy again.. just wait like 2 months or more and dye it again or just dye it a color that's close to your natural color

No, you don't need to chemically remove the color. You can apply a darker color over your hair. To avoid green tones or an unpleasant color, you will need to do a two-step coloring process. You can start by applying a reddish brown color to prevent your from turning green, then apply your desired color, which is medium brown.

Thank you :)

All you have to do is get your hair stripped!
You could have a bleach bath done on it, that way its not doing too much damage to your hair, it will just lighten the shade you have put on...

Your lucky really! I have almost black hair at the moment and I reaaaaly want to get it to a chocolate brown colour :(
