what the hell, reality check didnt work

So last night I had this dream where I am working at a parade or something and my job is to get people drinks. I'm really fed up with everybody asking me for stuff and I dont seem to remember even signing up for it (which of coarse I didn't) so I decided to get a little high on the job. Im with a few people that I really do work with and we are smoking weed. And this one girl pulls out this bottle of some drug that I don't think exists in real life. So I take a couple pills of the drug not even knowing what it does and I start tripping out, acting drunk and laughing at everything, :rolllaugh: it actually does make me feel quite good (placebo is a good drug:boogie:) so then we have to go back to the main restaurant and take orders or whatever.
At this point I'm walking back and I start floating. Naturally I assume its the drug. I then realize walking is no longer possible because my legs are not touching the ground so I start flying to where I'm going :fly:. I then think "what the hell?!? I didn't know drugs could do this! wait mabe I'm dreaming" I do the nose plug rc and nothing, I cant breath through my nose and I continue going to where Im going.
Quite frustrating, I missed a perfect opportunity to finally lucid dream. I know my nose wasnt plugged or anything so any theorys on why this didnt work? Has this happend to anybody else, quite odd, this was the first time I ever even remembered to do a RC in a dream and Im disapointed it didnt work. Im still waiting for lucid dreaming.

all reality checks can fail, including the famous nose rc. The nose rc is just less likely to fail. It has happened to me a couple of times. did you have a cold or something that would block your nose? that could be a problem sometimes.
