As the title says, i've had some strange dreams that seemed to prevent me from realizing i'm dreaming:

e.g.:
once i dreamed about a bum playing the guitar while i was sitting in restaurant... i enjoyed it but suddenly a waiter girl came out telling the bum to go away by saying "go away, we don't want any tourists (?) here"... i got confused (in the dream) and asked myself, why she said "tourists" although it was a bum, far from being a tourist... i wanted to ask her why she said that, but all of a sudden i was at a completely different place than before...

in another dream i vomitted on the floor in a room with lots of people. I'm sure they saw it, but they accused a bum (coincidence) standing next to me having done it... i wanted to ask why they were accusing him although they must have seen me vomitting... but suddenly the dreamscape changed and i couldn't ask anymore again...

now i suppose that my mind prevented me from realizing that i was dreaming... i hope it's not some type of a mind blockade or something...
however, i think that was really close from becoming lucid, right?
