Visualization and Hallucinations

I've been focusing a lot lately on trying to create waking hallucinations. While I've been successful at many different creations in my subjects, I've always struggled to create the true hallucinations in them.

Visualization is easy. Every subject I've worked with can create very elaborate scenes while in a trance. This isn't imagining these things in her head, she actually opens her eyes and sees them around her. One simple yet funny one had a woman who visualized herself floating six inches above the floor. She then spend the next few minutes trying to get "back" to the floor. I've had one subject who visualized being in a dungeon with other slaves. She could describe everything around her, and gave me a running description of what was happening.

The problem comes when awakened from the trance. A subject can easily see nipple piercings that aren't really there while in a trance, but they immediately disappear when awake. My latest attempts have used a continuation model to try to create the hallucination. For instance, my current submissive was told to strip naked while in a trance. She was then instructed that she would not feel naked when she woke up. She would still see and feel the same clothes she was wearing before. She would realize she was naked as soon as she stepped outside. I hid the whole session in amnesia and woke her up.

The instructions worked perfectly. But is it really hallucination? After realizing she was naked, I asked her about seeing her clothes. She couldn't remember seeing the clothes after the trance. She described it as more of not realizing she was naked, similar to putting on the wrong shoes or mismatched socks. She didn't see clothes where there were none, but instead never looked for the clothes.

I'm continuing my work on this one. Any suggestions, either through comments or email, are greatly appreciated!
