Congrats on your first LD! The dizziness is the headrush you'll get from realizing you're lucid. Usually people's first LD doesn't last too long because they get excited at realizing they've become lucid. Don't be scared either! Lucid Dreams are amazing and let you do whatever you please. It's like being granted the power of God. o_o

Oh and your account was probably erased. There was a reset to about 6 days ago. Something happened to the site last night. ><
