I think maybe there is a mix up here. I think Puffin was right. Reality checks don't induce Lucidity. Potential Lucidity can do reality checks but you have to have something give you the trigger to do them.

I think the question in the original post here is not so much about reality checks as to how to find a Lucidity trigger.

To me, I think it is important that the subconscious dreaming mind and the Lucid part of the mind are wanting to work together, and play together. The mutual enemy of both I think is Fear.
