To dream of your bed symbolizes a realization of your sexual needs and desires. You are becoming aware of your needs. If you are sleeping in your own bed then it implies that you feel comfortable and at ease. You are seeking happiness and solace in your home life. If you are waking up in different and/or unknown beds then it symbolizes the end results of your choices.
To dream that you are searching for a bed signifies your struggles to accept your inner sexuality. You are bothered by restrictions and limitations that you feel have been placed on you. It may also imply that you seek comfort and bliss at home.
To dream that you are going to bed with a stranger implies that you are too trusting and accepting of others. You need to slow down and scrutinize people before allowing them access to your inner feelings.
To dream that you are floating or lifting up into the air from your bed indicates your feelings of isolation and loneliness. Perhaps your character is too forward and intense for others to handle. You should relax a bit and try not to be too pushy with your beliefs and attitudes.
