If you eat something in a dream that you have never tasted before, it will usually be 1 of 2 things

1: It will taste like you imagine it would taste

2: It will taste like something similar

I dont imagine why you would be teleported or stopped from interacting with something like that. The same thing goes with smells, It will either smell like you think it will smell, or smell like something similar.

Sight is a tricky one though, im not really sure what to say about that
