In an electric mixer, add the thick cream, dream whip, creme caramel, heavy cream, milk, and condensed milk. Beat until thick and fluffy, with soft peaks, about 3 minutes or so.
Gently rinse the berries and pat dry, and cut the pound cake into large cubes.
Cut the pound cake into cubes, and layer a trifle dish like so: 1 layer of pound cake cubes, half the cream, 1/2 the cream, and half the berries (a mix of all the berries). Repeat with the second half of pound cake cubes, the second half of the cream and top with the remaining berries. Add whole strawberries and mint leaves to garnish, optional.
Let the trifle set for a few hours or overnight before enjoying!
