Irresponsible dreams

I keep having these weird, vivid dreams where I forget that I'm pregnant and do dangerous things. In last nights dream, I went out drinking and ended up getting so drunk that I couldn't move, and then I remembered I was pregnant and freaked out. The other night I had a dream that I was getting tattoos all over my body and on my pregnant stomach, and chain smoking cigarettes (I don't smoke, nor do I have any plans on getting another tattoo). Wtf is up with my brain at night? Lol
