What level are you? It took awhile for me to get the hang of dragon combat, but there were always human areas to level up in first, making the dragon combat easier. By the time I got to the Hall of Echoes I was level 36, so the initial memory eaters couldn't do significant damage.
Another..Hall of Echoes question - first dragon section
Entering the Hall of Echoes is suppose to be a one way trip; you shouldn't have been able to return to the battle tower, in human or dragon form.
If you return to the battle tower, can you take the teleporter to the Red Hammer tribe teleporter and re-enter the Hall of Echoes from there? By design the sections of the Hall of Echoes are exclusively dragon or human, so transformation is disabled, and it was the auto 'return to human' when teleporting back to the battle tower that messed things up.
