First off, I'd never had a succesful WILD, but this is the closest I've ever gotten:

I smoked one joint at about 8pm and went to bed at like midnight. I was not high but could still feel the marijuana. I decided to try a WILD. After about 20 minutes, I started to see very vivid hypnagogic imagery.

It soon turned to this scene: A field with a blue sky, and a house in the field. There was a man standing in the field, not talking, but inviting me to enter the dream. I then lost the vision and couldn't fall asleep for about 2 hours.

I am thinking that marijuana is very helpful to me for WILDs.
