…thank you for the advises…anyway i think i had never dream of fliyng in a airplane, my difficultie in consider the my controlled non gravity a dream sign is ,like i said the fact akways having a present feeling that i am doing somethig really natural, and if i understand you recognize a dream sign when you are doing something odd…but anyway i still want to try it…
anyway yesterday something happened… i was dreaming that i have found a non long seen friend and we were talking somethig about cristals rellated to our bodys chakras , and then i woke up , set on my bed and started to write the dream in my dream journal, but when i saw my writing esapiring i found out that i was still dreaming…but unfurtenly i woke up… but HEY IS A START ISNT IT??
because it is not the first time that situation happens maybe i should also start to considre that as a dream sign.anyway is a bit odd 
to consider my dream journal as a dream sign…
