I was sleeping tonight and woke up early because I had this horrible nightmare!!! This crazy girl on youtube was smashing a flute joint on a flute. lolololololol!!!!!!!

I mean footjoint, not flute joint. Ugh!

well its not about the flute specifically , but one night after a grueling day of basics training during band camp this year i immediately fell asleep. whew...good thing right? no. it was awful because all i dreamt about the entire night was that i was marching in the basics block. and then i had to wake up and actually go do that all over again for a whole day. it was awful.

HAHAHAHAHA!

So that's what happens to people when they retire and have to much time on their hands.

I generally have some kind of nightmare or anxiety dream before something major, such as getting on stage to play one piece , then having the others play something else, sitting on my flute backstage..and many more...

I had a nightmare that I was playing and someone came in during my preformance and kicked me off!!

I generally have anxiety about forgetting something. Not so much nightmares but when driving to a gig, I often look in my things to make sure that I have the music or even that I have my flute in the case.

i had a dream once in high school that my house caught on fire. my parents told me to leave my flute because it was insured and i could get a new one for free, but grab the piccolo because it wasnt insured.
so by the time the house was under control, i went back inside and found that everything in the house had been destroyed, except my flute.

then i woke up crying because i wanted a new flute.

haha!

i once had a nightmare that the keys of my flute fell off during a performance at music camp...OH WAIT! that actually happened! and as the director carried the flute across the stage you could hear other little pieces of it falling to the ground. thats when i told my parents i wouldnt wait any longer for a new flute...haha

oddly, i dont remember having any dreams about performing. but maybe i just dont remember them...

i also have anxiety about forgetting music sheets or the flute at home... lol
