Doctor Who episodes that I thought were Eccleston but not

So I spent a summer with my ex watching a lot of Doctor Who, and I guess I was not very sober for some of it. Here are a list of episodes that I have always thought to be Eccleston but not.

- The Christmas Invasion
- New Earth
- Tooth and Claw
- Army of Ghosts (no memory) but Doomsday (yes)

- Gridlock

- Partners in Crime
- The Fires of Pompeii
- Planet of the Ood

That's all. I just need a list to stay sane about it. Why do I have memories of them, but have no memories of Tennant? Or at least mostly?
