Truth, Fantasy or Fiction

For my A2 exam unit, I was given the theme of Truth, Fantasy or Fiction. After having read my exam paper a few ideas sprung to mind, some more obscure than others. I seemed to be fixating more on the idea of fantasy, I thought this was quite vast to play around with. I also liked the idea of creating something fictitious, or maybe bouncing fiction and fantasy off of each other. 
Naturally the first thing that came to mind when thinking of doing something to do with fantasy was fairytales. I thought of maybe recreating well known fairytales such as Snow White or Alice in Wonderland and combining them with modern day, for instance Snow White being hooked to an Apple iPhone as opposed to a real apple, or Alice in Wonderland falling through a rabbit hole but instead of being surrounded by clocks and furniture, you could perhaps see the pair of headphones she's dropped or her phone falling out of her hand. This was only an initial idea, I didn't want to go with it straight away. I thought I needed to give myself more time to come up with various new ideas in order to show some more development in this unit. I may eventually come back to this idea and at least play around with it, but we'll see. 
For Fiction, I came up with the idea of optical illusions. I thought this was also quite vast to play around with and a few little ideas came to mind while I was thinking about it. For instance I could do a little experimentation with different perspectives, such as having someone stand far away and make them look tiny whilst someone stood closer looks like a giant next to them. I could perhaps use this idea as one of my initial shoots, while I figure out what it is I will want to be doing. 
I don't seem to have been drawn in by the idea of Truth all that much. Unlike the other two themes I had no ideas spring to mind quickly and I had no inspiration with it. I forced myself to think of a little something to at least have some extra ideas but nothing really came to mind apart from one. I had the idea of photographing different meals, and the people eating them. I thought I could find someone who was underweight, and photograph her dinner plate, revealing the truth behind what she really eats. I thought of doing the same with someone overweight, and someone who's physically very fit. But then I thought this might offend some people, and I don't really know anyone who's underweight and I don't have access to anyone who is quite overweight either.
