I am not sure if I am imagining this or not but can breaking glass be used as a reality check? I thought I saw this mentioned by someone in a thread about reality checks people used but now I can not find it.

Only came to the forum yesterday, read very little, did not even know what lucid dreaming was until yesterday, had no intention of trying it but last night while in a dream I was sitting in the passenger seat of a car and tried to break the car window by tapping it with my fist. Somehow this seems to have registered with me as a RC when I woke up, sadly though I was too afraid to hit it too hard in fear of it breaking; guessing it is not a good method to use because of this? Or is not even a method at all?
