Independence of trials in non-parametric testing

I have a question regarding independence of trials in non-parametric
The experimental design that I have is as follows, there are three
conditions C1, C2 and C3. Each condition is of 1 min duration (e.g.
rest with eyes open for 1 min).
Now I am planing on dividing each condition into sixty 1sec fake
trials and then compare Time-Freq representation of C2-C1 and C3-C1
etc. for significance.
But I am not sure whether this style is statistically correct, since
the trials are fake and I am not sure if I can call them independent
of each other. I can theoretically count them uncorrelated (?) if I
separate these fake trials by say 300msec or something.
Just want to make sure I am going in right direction. Please let me
