Feeling of slipperyness
Feeling of being light and lifted
Feelings of joy
Seeing fragments of light
Body and mind will feel refreshed after visiting the astral
You may also have certain impressions after an astral travel experience.
You may also have dreams that "feel" differently than regular dreams. these dreams are often recall experiences of information you learned or gathered on your travel experiences.
Hearing music and/or having a song in your head when you awaken sometimes is a way your mind brings back travel information.
