When/if I decide to actually try this. I'll report back.
This leaves me thinking that my idea is kind doomed from the start.
You would not remember your lost wallet's seed using hypnosis but at least you will remember what type of wallet you have used to access that wallet but the chance of you being able to open it easily after hypnosis is still pretty low. I'd suggest that you give up on the hypnosis idea and try other means to recover your wallet.
